Video Transcript for etrailer Camper Jack EJ-3520-BBX Review

Today we're going to be taking a look at the Electric Jack for A-frame trailers. This jack is going to feature a lift capacity of 3,500 pounds. It's going to let you raise and lower your A-frame trailer. The jack is fused protected, so right here is going to be our fuse holder. That's going to have a 500 volt 30 amp fuse. On the front of the unit, right here, are two, very easily accessible toggle switches.

These are located on the front of the housing. That way, you can easily operate the jack. You're going to have your on and off switch, which is going to control the LED light. Then you're going to have the extend-retract switch, that controls the up and down movement of the jack. The LED light is going to illuminate at a downward angle to help you focus on your coupler. There's a lens here at the bottom that allows light to come through.

That's really going to come in handy when hooking up, or disconnecting at night, or low-light conditions. The unit comes with an emergency crank handle, which is this piece right here. If you ever experience a situation where maybe you don't have power for some reason, you can still operate your jack manually, if needed. The connection point for that handle, is located right here, at the top of the unit. Now, this is a nice sealed cap, that way it's going to do a great job at keeping out dirt, and moisture, and grime. That's nice, easily accessible for those situations where you may need to manually operate the jack.

Again, the handle is included to do that. Also, at the bottom of the unit, is the included drop leg. That's going to allow for increased lift, and it's going to save time when raising or lowering your trailer. The pin and clip is going to hold the leg at the desired location. At the bottom of the drop leg, is the welded on round foot plate. That's going to offer a diameter of 5 1/2 inches.

A foot plate does a great job at spreading out the applied weight, especially on softer surfaces, to help prevent sinking. The unit is made from a steel construction. It's going to have a black powder coated finish on the outer tube. Then on the inner-tube, and on the footplate, as well as the drop leg, we're going to have a zinc plated finish. All of that's going to do a great job at resisting rusting, corrosion, making sure that this unit lasts a long time, and that it looks good for a long time. The housing right here, this is all from a durable black plastic construction. Now, it is a simple bolt on installation. The mounting pattern, here on the mounting plate, that's going to allow you to you attach it to any standard A-frame trailer that has an attachment point for a round trailer jack. Then your mounting bolts are sold separately, but it does come with flat washers, and serrated washers. It's going to feature a single wire design. This is designed to wire to a 12 volt power source, with the included power lead. When it comes to grounding the unit, it's not a separate wire. It's actually going to ground through the mounting hardware. This power lead, I took a measurement from the bottom of the fuse holder, to the end of the power wire, and got a measurement of around 65 inches. That gives you an idea of how long that is. A few other measurements that I want to go over with you real quick, just to give you an idea whether or not this is going to work for your application. One of the measurements we like to do, is a bracket height measurement, with it retracted and with it extended. I'm measure form the ground to the bottom of that mounting bracket. That's going to give us a measurement of right around 9 inches. I did that same measurement with the jack fully extended, and got a measurement of 28 1/2 inches. If we subtract those two measurements, it gives us the lift, or travel, which is 19 1/2 inches. Now, the drop leg provides an additional lift or travel of 5 5/8 of an inch. It gives it a total lift, or travel, or 25 1/8 inches for this jack. Another measurement that we like to do, is a clearance measurement. We want you to make sure that you have enough clearance, or enough room from the mounting surface to the top of the jack, making sure that it doesn't interfere with any other components. If we take that measurement, that's going to give us a measurement of 20 1/2 inches, and that was measuring from the bottom of the mounting plate, to the very top of the unit, which is right here, at that knob that allows us to gain access for the situations where we need to manually operate by connecting our crank handle. The outer tube gives us a diameter of 2 1/4 inches. The inner-tube has a diameter of 2 inches. Real quick, I want to show you the drop leg, and then we're going to hook it up to power, so you can see how it functions, and how it operates. This is our drop leg, and, again, on the bottom, is our foot plate. It's got 4 different mounting holes on there, or adjustment holes. Those holes are separated on center, apart from one another by 1 7/8 of an inch. That's going to be your incremental height adjustment. All right, we're going to go and hook it up to power. Want to make sure that we have a good ground connection. All right, so you can see that that light is on. To extend the jack, we just push up on the toggle switch. It's got really nice movement to it. It's pretty quiet for an electric jack, as well. Really nice movement, and again, that will go all the way up. To lower it, just push on the down button. Now, it does have a stop line, right here, that way you don't exceed the fully retracted position. Also, when you hit that, the motor will actually stop, which is a great indication to let off of the switch, so we don't cause any damage to the motor. The LED light, you can see that has a clear lens, which is going to allow light to come out, but also on the bottom, it has a lens, which casts light at a downward angle. Which again, is great for those situations where you're having to hook or disconnect at night, or in low-light conditions. That's going to do it for today's look at the Electric Jack for A-frame trailers.

Would have to say 4.5 on the rating only because of the installation instructions. On installation instruction #4 it tells you how to assemble the hardware and then directs you to a figure above. This figure is nothing more than the plain jack. Then it tells you on #6 to position the fuse holder as close to the power source positive terminal as possible. The fuse holder comes in already attached to the jack adjacent to the jack control switches. Ease of installation other than above. Common sense will get anyone past those directions. Jack operation was perfect after installation. Test of jack showed it works as advertised and I can't wait to use it in the upcoming camping trip. Ordering, customer service and shipping/receiving was excellent. I was informed on the delivery date and status of shipment by ETrailer to whole time. Properly packaged and the unit came in in excellent shape with no defects. As you can see in the pictures it is a clean install and I added a very nice cover which was also sold through E-Trailer. Another nice product to finish a successful installation. 379431

The old jack on our tent trailer (2" outer pipe) was getting harder to crank, and just didn't have the reach of this 12v powered jack I read about in an eTrailer email. I felt somewhat sure of the measurements and ordered it. It came on the third business day which was terrific as we're headed on a 5,000 mile odyssey up to Maine and through New England starting three days later. I rechecked the measurements, and note that, without the footplate, the lower level is 7" with about an additional 1-1/8" reveal of the inner 2" pipe. Installation was basically easy, and the holes lined up perfectly to re-use the original bolts along with the furnished washer hardware. In my case, the lower plate was LESS THAN 2-1/4'' and I spent a few minutes cutting with a Dremel tool to accommodate the lower pipe. The electrical hook-up was simple. I normally leave the negative connection to my battery detached, and this unit won't work without it re-connected since it grounds the frame. The upside of that is that you don't need to have an inline switch to thwart mischief, simply disconnect the negative cable to your trailer battery. This unit gives me much more range of height, the motor is powerful and quiet, and moves at a reasonable pace. The included footplate adds more height, but I'll use a short, flat one as a matter of convenience. Everything was as described, except for the measurements. I'd note that the top box is a full 8" deep. For us, that means I can't open the back gate of the tow vehicle when attached, but we'll change our discipline and put last minute items in the storage area of the trailer. Well done, eTrailer! 441983

After four camping trips with a manual tounge jack, I decided to buy an electric one. My last camp site was 8 inches off level and that was enough for me. I installed the EJ-3520-BBX this afternoon. Everything worked fine except for a few tweaks. The lower a-frame hole for the tongue jack was too small so I had to use a sanding drum on a drill to open it up so it would fit. Not a big deal to me but might have been for someone non-mechanical. Not sure if that was a trailer problem or a non-standard tube diameter. The jack light (three LED's mounted on a circuit board) under the jack screw and motor cover had become completely dislodged from its slotted mount and was just floating around in the plastic housing. I took the cover off, re-mounted it and used stainless washers under the cover screws to prevent them from digging into the plastic when I put the cover back on. The jack works as advertised, and even picked up the rear of my Ram 2500 Cummins several inches to facilitate putting my Blue Ox WDH sway bars on. The tongue weight of my trailer is 650 lbs so I'm guessing it picked up well over 1500 lbs. I found an old dry bag and it fits perfectly over the jack to protect it from the weather. So far I am pleased with it but wished the manufacturer had used and automotive type spade fuse instead of the antiquated tubular glass fuse. Only time will tell as to the durability and longevity of this product but I am optimistic and there is a manual crank included if something goes down. A tick over a hundred bucks can save one a lot of aggrevation! 443807

I bought this jack after doing a lot of research. The conclusion I came to was that most of these electric jacks are basically the same design with a different name stamped on them. I like how this one has an inline fuse, a higher lift range, and an adjustable footplate. I read a lot of forums, Facebook pages and reviews on a variety of websites. Etrailer offered the best option for what I was looking for. This jack is well made. It's heavy and solid. It was super easy to install. If you can't install this, you probably shouldn't be pulling a trailer. It was literally 3 bolts and a ring terminal. The wire lead does not come with a ring terminal attached. You have to add your own, which is no big deal. It comes this way so you can cut the excess wire to fit your application. It also came with 3 washers and 3 star washers to ensure a good ground connection on the wiring. The light is super bright as well. Etrailer kept me up to date the whole way through the ordering and shipping process. This was my first purchase from them and it was a great experience. 438735

The Ram jack was very easy to install and hook up!! The motor runs super quite and has plenty of power to raise and lower our camper trailer. Only thing wrong with it was the plastic housing has a crack in it which I think happened in shipping. 394778

The EJ-3520-BBX electric jack arrived three days after I ordered it. After removing my bulldog jack from my Sundowner horse trailer, I attempted to install the electric jack; however, one of the three holes in the mounting plate did not line up. After a little work with a round file, I was able to install it. I removed the access cap on top to make sure the manual crank would work(it did); however, when I replaced the cap, the stop tabs immediately broke off. I wired it to the trailer battery and tested the unit. The light and lower/raise switch worked as they should. I cannot lower my tailgate; however, I knew this before I purchased the product. In the retracted position, I have more ground clearance with this jack. 447566

The jack was not well put together. Some screws on the motor cover were falling off and the LED light was loose in its housing. The housing itself was installed incorrectly. I had to take it apart to put it together properly. Also, the cable where the fuse connection is was exposed. I used electrical tape to seal it. Not good for something new! After that mess the install was pretty simple. The jack lifts my trailer easy enough. On paper, this is the only jack that has long enough travel and drop leg to level our trailer on our driveway. The black also matches the trailer well. Time will tell if it holds up to normal use. It's on a Winnebago Micro Minnie 1706. 395461

Excellent product! This was super easy to install, took longer to look up what wire I needed to connect the jacks power lead to on my trailer that it did to do the actual install! This thing works great and has made life so much easier for my wife, hooking and unhooking our 7x16 cargo trailer is a breeze now, she often does craft shows. If I had another trailer I'd buy this jack again. 446201

I just installed this jack. The installation went easy but I did need a hammer to get the jack past the bottom hole in the trailer mount. Hook up to the battery was easy, just crimp on a ring terminal and connect it. I don't think this jack is very weather proof so I covered it with a canvas and suggest this is a necessary step. Only time will tell how it works long term but the price for this unit is very competitive and the jack seems well made. It was important to me to have the ability to raise and lower the jack manually and this is an option on this jack. 435649

From super customer service from Natalie L to my first order being placed, I was extremely happy. I had just found this company on line and was leary of what I might encounter. Natalie L was customer friendly, courteous, and out going !! Her knowledge of the products was unbelievable !! The prices were very competitive and the shipping time was way faster than I had expected. From now on this will be my first choice for all my RV needs. Many thanks for a great experience !!! 450564

I installed this on a 2015 Keystone Hideout 24BHWE. It bolted right in with my existing bolts and just needed some heat shrink tubing and a ring terminal crimped onto the wire. Now lifting up the tongue enough to get the weight distribution hitch on is a breeze. Leveling out the front/back is quick and easy too. I have good clearance at the bottom of the jack pad when it's in the shortest configuration. 396362

My electric trailer jack came at noon today. Got home from work at5:30 and had all hooked up and running in 25 minutes! Easy to install! Was worried about the motor head being too tight against propane bottle cover...but it fit perfectly!Runs super smooth so far. I put up with a hand crank tongue jack for far too long. Seems like a good product for a reasonable price!! 394253

I am very pleased with this order it operates very quietly and is going to be a great asset on my trailer.cost less then any others I have seen except some on other site, But I would rather buy from a company I trust everything I have bought from etailer has been top quality. 373795

Not happy. Jack did not fit the bottom plate hole. I had to roto-rootor it for it to fit. Also instructions were very vague. Thank goodness for youtube. Also it was not clear whether or not item comes with an in-line fuse. Mine had none. Nowhere does it state what size fuse to use. I'm hoping a 30 amp is not too big. Other than that so far so good. 446937

The product we ordered was out of stock and we had to wait for it. They gave us many other options but we didn't need it right away. They sent follow up emails to let us know the status of the order. When it came from the manufacturer they sent it to us very quickly. Great customer service. We would definitely buy from them again. 436693

We were really impressed by the quality of our new 3500 Jack. But as it is winter here in Michigan we can't give you a review on how well it works. We can tell you that Etrailer was one of the easiest site that I have been on, not only with ordering but also with tracking. We will be ordering from here again. 335339

Installed easily and works well on my 2018 Viking 21FQ travel trailer. As with any product purchased from any source only time will tell how well it holds up. I've noticed comments by others about how slow it is but I think the speed is just fine. No need to have it go up and down like a rocket ship. 445888

Currently only used once after installation to park the trailer for the winter. Will be using this summer. Seems like a quality unit especially for the price. Functioned well on the test after install and raised the trailer almost full height for a sloping driveway. 360746

The jack works great not the fastest jack I’ve ever seen. But it is extremely quiet which is a big plus for me. My old jack was noisy it was embarrassing if we got to a camp ground late it was so noisy it drew a lot of attention. 450103

Just installed it. Good install. Have not applied voltage yet. This is installed on a 14' utility trailer w/o battery. Can I wire the B+ to a 7 pin plug? If so which terminal?s 442937


Comments

David, Thank you for your review on EJ-3520-BBX. This electric jack uses a 12 volt system so it can be powered by a 7 way. The black wire on the jack needs to be connected to the 12v pin on the 7 way. Your best option to power the jack is add a battery to your trailer and provide it with a trickle charge from the 7 way. Make sure the 12 volt circuit from the 7-way is connected to the positive side of the battery terminal. This will only maintain the charge not charge a depleted battery. We have chargers like part CTEK56158 to charge a depleted battery. I hope this helps.

Do you have a question about this Camper Jack?


  • Recommended Electric Trailer Jack for an A-Frame Trailer With 700 lb Tongue Weight
  • I recommend using the etrailer.com Electric Jack with a Footplate, part # EJ-3520-BBX, for A-Frames. This trailer jack is rated for 3,500 lbs so it will have more than enough power to lift and lower your tongue weight of 700 lbs. This trailer jack has a total lift of 25-1/8 inches and comes with an LED light that shines down towards the coupler to make connecting or disconnecting your trailer in the dark much easier. Another great feature about this electric trailer jack is that it has...

  • Availability of an Electric A-Frame Jack for a 24 Foot Cargo Trailer
  • The Etrailer Electric A-Frame Jack, # EJ-3520-BBX, would work well for your enclosed trailer. When looking for an electric jack for a trailer you will want to find a jack that will handle the trailer's tongue weight. Typically, the tongue weight of a trailer will be 10 - 15 percent of the gross trailer weight. So, if your trailer's gross weight is 10,000 lbs, then the tongue weight will be 1,000 - 1,500 lbs. The best way to power an A-frame jack is to have a battery installed on...

  • Recommended Electric Tongue Jack For Toy Hauler
  • For your toy hauler, I recommend the Electric Jack w/ Footplate - Drop Leg # EJ-3520-BBX. This jack has a 3500 lb capacity and will lift 25-1/8 inches total. That lift is including a 5-5/8 inch drop leg travel. It has the outer tube diameter of 2-1/4 inches to fit your A-frame's jack hole diameter. If you are interested in a jack that requires less power draw and uses a low-friction ball screw to reduce wear, I recommend the Husky Brute # HT87247. This jack will also fit your application...

  • Electric A-Frame Jack Recommendation for Jayco Jay Flight Travel Trailer
  • For a Jayco Jay Flight travel trailer that weighs 6100-lbs dry you will want an electric tongue jack rated as high as possible to ensure the jack does not have to work too hard; this will help it provide a longer service life. All of our bolt-on a-frame electric tongue jacks are shown on the linked page. These offer varying amount of lift, from 14- to 25-inches. We offer a great-value option in parts # EJ-3520-BBX (black)and # EJ-3520-WBX (white). This jack has 3500-lb capacity, 25-1/8-inches...

  • Recommended Electric A-Frame Trailer Jack for 2008 Puma Tandem Axle Trailer
  • For your Puma tandem-axle travel trailer that weighs roughly 5300-lbs I suggest either part # EJ-3520-BBX (black) or # EJ-3520-WBX (white). This jack has 3500-lb capacity, 25-1/8-inches of lift and it includes a drop leg. It offers outstanding value as compared to similar electric a-frame jacks shown on the linked page.

  • What Is The Warranty On The EJ-3520-BBX And Is It Weather Resistant?
  • The etrailer.com Electric Jack w/ Footplate - Drop Leg - A-Frame - 25-1/8" Lift - 3,500 lbs - Black, # EJ-3520-BBX, comes with a 1 year warranty on parts. It is designed to be water resistant with its zinc coating and plastic housing, but you could put a cover on it if you desire like the Ultra-Fab Protective Cover for Electric A-Frame Jacks - Vinyl - 12" x 14-1/2", # UF38-944020, to prolong the life of the jack.

  • Replacement 3500-lb Electric Tongue Jack to Replace Arksen 12 Volt Jack That Won't Raise or Lower
  • If your electric trailer jack's motor is operating but the jack does not move up or down this suggests a problem in the gear box connection between the motor and the jack. This issue would often tend to include some bad noises. Since you can manually crank the jack up and down it would appear its main screw mechanism is still okay. However, it can happen that a jack will appear to be getting full power to operate (say, for example, if its built-in lights do light up) but still not operate...

  • Troubleshooting an Electric Jack that keeps Blowing Fuses
  • Sounds like there is an electrical short somewhere in the jack circuit. Inspect the trailer jack wiring to see if there is any loose connections and frayed or damaged wiring that could be shorting causing the fuse to blow. Also, if the jack has been extended too far, then trying to move the jack back into position will draw more amps then normal operation. This would cause the fuse to pop. Since you stated that you got the jack to start to retract again, then internal damage to the unit...

  • Would Etrailer Jack # EJ-3520-BBX Work Well on 2007 Coachman Captivia 28
  • Your tongue weight would be around 680 to 1,000 lbs most likely which would be easy work for the Electric Jack w/ Footplate # EJ-3520-BBX you referenced as this has a capacity of 3,500 lbs. My favorite powered jack to recommend is the Husky Jack part # HT87641 as it has bearings in the screw which allow it to operate quicker and smoother. It also shuts off automatically before topping or bottoming out. Other jacks will allow you to go too far with the jack but in doing so you damage...

  • Electric Jack Recommendation for 2004 Timber Lodge Camper
  • I looked up pictures of your 2004 TimberLodge camper and it has the propane tanks very close to the back of the trailer's jack. So for a powered jack that will fit well with that setup you'd want the etrailer.com powered A-frame jack part # EJ-3520-BBX which requires very little clearance behind the jack tube.

  • Does 3,500 lb Capacity of Electric Jack part # EJ-3520-BBX the Trailer Tongue Weight Capacity
  • The 3,500 lb capacity of the Electric Jack part # EJ-3520-BBX that you referenced is the lifting capacity of the jack. What that means in a trailer scenario is that it would be able to lift the tongue weight of a trailer up to 3,500 lbs. When you connect a weight distribution setup to a trailer you end up lifting the rear suspension of the vehicle as well to help get the spring bars on as that relieves the pressure. So that's when the extra capacity for the trailer jack is useful.

  • Installation Of An Electric A-Frame Jack On Trailer with 4 Inch On Center Triangular Bolt Pattern

Unfortunately, the Electric Jack w/ Footplate - Drop Leg - A-Frame - 25-1/8" Lift - 3,500 lbs - Black, # EJ-3520-BBX, is only a fit for the standard 3 inch on center bolt pattern.

  • Troubleshooting Weak Ground Preventing Electric Jack EJ-3520-BBX From Functioning
  • You did some excellent troubleshooting and because of that we know the issue is ground related. What is going on with your trailer is that it does not ground sufficiently through the trailer frame. What you can do is ran a ground wire from the mounting plate of the jack to the main ground wire of the trailer connector or you can try improving the ground strap from the connector to the trailer frame and either way will get the jack working.

  • Can the Footplate on the Electric Jack w/ Footplate # EJ-3520-BBX be Replaced with a Wheel
  • You can replace the footplate with a wheel for our Electric Jack w/ Footplate # EJ-3520-BBX. Since the jack has an inner tube diameter of 2" the Replacement Heavy-Duty, 6" Caster for 2" Diameter Bulldog Jacks # BDCP555 would work, but the 3,500-lb weight capacity of the jack would be dropped down to the 1,500-lb weight capacity of the wheel as that would be the weakest part of the jack. Since most electric jacks are used for heavier trailers I recommend keeping the footplate on your jack.

  • Recommended Electric A-Frame Jack for 2006 Eclipse Attitude 21AK Travel Trailer
  • When selecting a powered tongue jack for a travel trailer like your 2006 Eclipse Attitude 21AK it is best to over-spec the jack, meaning to select one that has more weight capacity than you absolutely need for the trailer. The Attitude 21AK has a specified weight of 6100-lbs so I suggest a tongue jack rated for 3500-lbs. This will let the jack work less hard to do the lifting it needs to do and that tends to help such items last longer. If value is a key factor in your decision go for...

The side jack makes me think 5th wheel or stabilizer jack but I will give all recommendations. If your 1993 Jayco Eagle is a 5th wheel trailer, I recommend the Stromberg Carlson Electric Landing Gear Set - Weld On - 34-7/8" Lift - 5,500 lbs # LG-1.

  • Can etrailer.com Electric Jack w/ Footplate be Powered from 7-Way Connector
  • The etrailer.com Electric Jack w/ Footplate # EJ-3520-BBX referenced in your question uses a 12 volt system so it can be powered using the 7-Way connector on your vehicle. To do this, you will just need to connect the black power wire from the jack to the 12V pin location on the connector. With that being said, powering a trailer jack from the 7-Way is not always the best option as it could overload the circuit.
