Purchased this jack to replace a manual jack we have on our cargo trailer. Swapping it out was easy-peasy! Had an issue getting power to the jack; called for assistance and had enthusiastic help from Nicole. Turns out it was our brand new truck that was the problem...a smart vehicle sometimes needs to be outsmarted in order to allow power to the 7-pin. Overall, very pleased with the purchase and the customer service. Highly recommend! 727294

Review from a similar etrailer 3.5K in Camper Jack


After purchasing a small camper and using the hand crank jack two times that I would look for an electric jack to replace it. Many of the jacks cost more than I wanted to spend. Then I found "etrailer.com". The prices were reasonable. I ordered Item EJ-3520-BBX electric jack. I have had it for a year now and have used it many times. I truly a happy camper. It has saved me time and energy. My wife can operate it and has no trouble letting me fish while she breaks camp with no help at all. The follow up service is great. Check "etrailer.com" before you buy any where else. 566675

Functionality is very good but the top plastic cover is not made of good/strong material. It broke but still works fine. Not sure if replaceable but I'll use it as long as it works. Suggest to keep the manual lifter inside the trailer in case electric is broken. 662719

What a easy upgrade for your camper. I ordered and received in a few days. etrailer just does it right. Install was so easy, anyone can do it. No more cranking for me, push the button and like majic, you can take your trailer up or down. I also purchase the cover to keep the weather of the motor and controls. It is nice too. Thanks Lisa D for your great service. 496356

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

Review from a similar etrailer 3.5K in Camper Jack


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


Comments

I have had my trailer out a number of times in the past year. The jack has worked flawlessly. The only down side is my tailgate will not lower all the way with the trailer hitched up. It means I have to do a bit of preplanning but other wise its not a problem. I still keep the jack covered and suggest this is necessary for long life.

This inexpensive travel trailer jack arrived after only two days via UPS. Securely packaged. It is truly a quality item! Very easy to install and works great. The manual handle is a bonus in the event it is ever needed. Be sure to follow the instructions making sure the three screws on the plate are solidly grounded using the supplied star washers. I can honestly say that this jack is one of the best items I've ever bought for my RV. Thanks etrailer! 480612

Review from a similar etrailer 3.5K in Camper Jack


I purchased this jack to replace my tired 10 year old camper jack . I ordered it at 10:00 AM Monday and as promised by Ian it was at my doorstep on Friday just in time for my weekend getaway . Installation was a breeze . I gave the product a 4 out of 5 for a few reasons . First , I was not able to see the manufacturer of the jack before receiving it . Which made name brand comparison pricing difficult . However I feel pricing was on target . Second , I feel that the jack should come with a battery terminal end connector and new mounting bolts with the hardware that was included . This didn’t pose any difficulty to me as I had hardware at hand but for some it will mean a trip or two to the hardware store . Third , once installed , at least with my truck and trailer , unless the truck and trailer are perfectly aligned and level the jack motor gets in the way of opening the tail gate . On first use I noticed it was much slower than my original but the strength made up for it . This jack had no difficulty or hesitation lifting my truck and trailer for load distribution and anti sway bar installation . I would recommend etrailer and this product . Time will be the final test of its durability . 562097

I’ve owned this jack for a year now and it’s still working like new . The Motor still gets in the way of the tailgate from time me to time but I’ve learned to work around it . The strength of this jack is incredible ! I’d recommend it for its value and retailer for its customer service !! Since purchasing this jack from etrailer I’ve done business with them again and I’m extremely satisfied . If I need a part they’ll get my business.

I have installed the tongue lift on my camper . It fit perfectly and it operated just fine . No problems so far . I used a small battery clip on the hot wire from the lift and when I need to use it I simply clip it to the 12 volt battery on my camper . The way my camper is wired the ground wire from the camper to the battery has to be hooked up in order for the lift to operate . But I am very happy with it so far . By the way what is the warranty on the lift ? Sending pictures also of installation . 471421

Review from a similar etrailer 3.5K in Camper Jack


I installed this jack about two weeks ago on a 22' travel trailer, and have only used it 3 or 4 times. This is the first electric jack I have owned. It was a breeze to install, only took about 10 minutes to replace the manual jack. If I would have known how easy they were to install I would have replaced my manual jack several years ago. I didn't rate it 5 stars because it operates slower than I expected, (may be normal) and I originally had trouble getting the jack to work. Seemed to be stuck or the gears out of sync. I took the manual crank and worked the jack back and forth a few times to get it going. Works good now. For the price I'm very satisfied. Only time will tell how the jack holds up, but if I can get 3 years or so out of it I will be happy. Sure beats cranking the trailer up and down by hand. I had a an old laptop case that I am using to protect the motor unit from the weather and it seems to do the job. 489608

Still very satisfied with this jack. After one year of moderate use I have had no problems. Its so much easier than the manual crank type. Thanks ETrailer!

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

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

Customer Service is number 1!! Mr. George is awesome on ensuring you receive the product and are satisfied. I had the electric jack installed in less than an hour. That included reading instructions, acquiring the tools, running electrical check for hot wire, and replacing the tools. I used the electrical box under front of the trailer for the power. To ensure I would not chaff the wire, I selected a hole in the box and drilled it to 3/8". I then drilled a hole in a valve stem cap so the wire would slip through the valve stem cap. I then pushed the cap into the hole and wired to existing electric wires with wire cap. 491854

I put the RAM hitch on the trailer and did not have any problems. Bolted in place and hooked the electrical up without any issues. I have not taken the camper out yet because of rain, but tried the light and up/down on the hitch and seems to work fine. Service at etrailer is very good. The only reason I did not give five stars is the instructions for installation are not very good. They tell you to refer to a picture and the picture is not there. It also tells you to install the fuse holder as close to the battery source as possible. However, the fuse holder is already in line and close to the unit. Minor issues as it is simple to install. One call to etrailer to check about the placement of the fuse holder and good to go. 523903

Very solid and heavy duty jack, with bright LED lighting, manufactured by Ram. Adjustable foot piece for quicker adjusting... Jack pretty easy to install, with single wire electrical connection and 3 bolts. Jack has low gear ratio and foot shaft moves slowly, but has plenty of power to lift front of trailer. Plenty of clearance behind jack for propane tank cover on our Airstream. Replaced more expensive model that was bent at mounting flange being winched onto transport trailer. 474270


Comments

Jack is still slow and steady and has worked perfectly since installation... The adjustable foot unit is about an inch too tall for at lowest position some sites, based on low hitchball height of our tow vehicle, but we have used the shorter foot from prior jack as an alternate, and that solved problem...

The Jack seems to be great quality and was very easy to install. At first I was a bit perturbed with the lack of detail and small font of the one page directions, but it’s as simple as 3 bolts and one wire to the battery(the hack is grounded inside). It raises my 2017 Jayco Baja much higher than stock crank jack. I hope it lasts the test of time as I am very happy with it this first day. The light seems bright as well. 497245

Great customer service. After receiving a damaged unit on Tuesday the 26th, I called and spoke to Sal and emailed him pictures of the damages. Also they had originally sent a white one but I had ordered a black one. They immediately shipped a new black undamaged unit and I just received it on the 29th and got it installed. The damaged unit is on it's way back to E trailer. I have purchased many items from Etrailer and am very pleased with their service. 463641

I checked out a lot of reviews before buying this jack. Part of my decision was based on the price point and that it has a higher lifting distance than some of the others. Installing the jack was a snap. Just mount the trailer on your trucks hitch for temporary support during the change over and you're off to the races. The bolt pattern matched the old manual jack so no issued there. Even with the washers that come with the electric jack my original screws were still long enough (you will need to reuse yours, the electric jack doesn't come with any). I simply zip tied the wire to the existing wire bundle under the A-frame. I did buy a ring kit to attach the end of the power wire to the battery properly. I did not cut any length from the wire as some reviewers had advised. Just coiled up the excess. The jack worked right away. I think I heard my aging shoulder breath a sigh of relief. Afterwards. I did order a cover for the electric jack head. I figure the unit will last longer if the sun isn't always burning down directly on it. So far, I would recommend this jack. Time will tell. 543425

Ok.... the customer service from ETRAILER totally saved the review! These guys are incredibly awesome. I ordered 2 of the jacks. The first came with a broken housing cover , the light had beed disloged, and the up down switch was wired backwards. (Up would put the jack down and down would put the jack up) Solution? Glad you asked! I contacted ram about the cover.... waiting! The light was easy to correct, just had to slide it back into the slit that holds it. Switch, well.... if-your2 not comfortable with wiring, I recommend not even attempt to rewire. I just popped it out of the cover, twisted 1/2 turn, popped it back in. Total time to correct.... 8-10 minutes. Total time to install, 15 minutes. Total job less than 30 minutes. Would I recommend this jack... YES. Despite a shipping issue to crack the housing ... its easy to install, price right, powerful. I dont have to hand crank. Simple correction to the switch. And they could use some r&d improvment on the light... but excellent jack! It does what i meeded it to at an affordable price! 494266

I received the tire package and electric tongue jack today. Everything arrived without damage and installed easily. Although I cannot predict longevity, I can say that the items seem of high quality. The new tires transformed my travel trailer. About the only negative thing I can say about the tongue jack is that it is a little slow but looks sturdy and well built. 569519

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

Have no idea why people rate this jack less than 5 stars? But I have just put it on and tested for 1 minute. Sure it's a bit slow, but you can still drink your beer while adjusting! It has to be slow in order for gear ratio to move 3500lbs, a no brainer. And to be honest, I am a perfectionist, and it took me almost an hour to properly install...between not scratching the pole with a socket wrench and having to run to the hardware store for an end terminal. This comes with a bare positive wire. I wanted a terminal so it can be easily removed from battery each fall. 491452

Review from a similar etrailer 3.5K in Camper Jack


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

Review from a similar etrailer 3.5K in Camper Jack


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

Review from a similar etrailer 3.5K in Camper Jack


I just got this, opened the box, hauled it out to my trailer (which was stuck due to a frozen 'jack; already removed) and had this one installed and wired in about 5 minutes. And it worked; confirming my diagnosis that the old one was 'toast'. The only improvement that I can think of would be to incorporate a 'hanger' for the 8 pin plug when not in use.... So I pulled the old one off the dead jack and ziptied it to the main upright. Problem solved. The only reason there are only 4 stars is that it worked TODAY. In a month I may have to review again but shipping was fast and free. The jack worked well. So..... so far; no complaints! 571675

Review from a similar etrailer 3.5K in Camper Jack


This jack was easy to install and is exactly what I was hoping it would be. Etrailer has excellent customer service! When my jack was originally shipped it was not able to be delivered to me due to flooding. The jack was shipped back to etrailer. All it took was one phone call when the roads cleared and without hesitation they immediately shipped my jack back out. I received it within a few days. Above and beyond great customer service and just as good of a product. Will definitely use etrailer in the future. Thank you! 574502

Review from a similar etrailer 3.5K in Camper Jack


This was an excellent choice. It has lifted the tongue of my very heavy 16 ft enclosed trailer, fully loaded with approx 7000 lbs, many times. It has never failed to operate just as it should. And, the price was excellent. Pushing the button versus cranking a jack is a no brainer. Would buy again without hesitation. 571933

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

Review from a similar etrailer 3.5K in Camper Jack


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

A year later, the electric jack has worked flawlessly for us over the past year. I still give the unit a 5-star rating and enjoy the solid performance of the electric trailer jack.

The trailer jack arrived in great condition and as described, it took about 15 minutes to take the old one Ok ff and install the new EJ-3520-BBX. Wired direct to my positive side of the RV battery works flawless, on my 2017 Jaco Jayflight 32BDSW. Thanks for fast and easy search on your website. 538711

  • Troubleshooting Electric Trailer Jack with 7-Way Plug That Does Not Function Consistently
  • An electric A-frame tongue jack like # EJ-3527-BBX or # 3370093500 that has a pre-wired 7-way plug will rely on the ground and +12V contacts within that plug to deliver operating power. Jacks may not function with less than 12 volts. Those contacts are located, respectively, at the 5:00 and 11:00 positions on the plug as you look at it. Please refer to the linked photo. You might try an aerosol electrical contact cleaner like Caig De-Oxit to see if that restores reliable operation. I...

  • Troubleshooting Ram 3,500 lb Trailer Tongue Jack Working Intermittently
  • I reached out to my contact at Ram and he said that their electric jacks, like part # EJ-3520-BBX, # EJ-3520-WBX, or # EJ-3527-BBX have one fuse and it is located on the black wire where it enters the housing. From what you described I believe your problem is a bad ground. These jacks ground through the mounting hardware so if the connection isn't solid and constant it can cause the issues you are having. What my contact recommended doing was taking some of the paint off of the trailer...

  • Recommended Electric Tongue Jack Upgrade for a Winnebago Winnie Drop WD1710
  • For your Winnebago Winnie Drop WD1710, I recommend the Electric Jack w/ Footplate part # EJ-3527-BBX because it does not require any wiring, there is a drop leg so you can raise/lower the trailer quicker, there is an LED light for use at night, and it comes with a manual override for use in case of power loss. This jack will be a direct bolt-on fit for your Winnie Drop.
