How to Determine the Lift Capacity You Need in a Jack

A trailer jack is designed to lift the tongue of your trailer so you can connect the trailer coupler to your hitch ball. To do this, you'll need a jack with a lift capacity high enough to handle your trailer's tongue weight.

Tongue weight is the amount of weight that your trailer applies to the back of your tow vehicle. Typically, your tongue weight should be 10-15% of your total trailer weight (trailer + cargo). In other words, a 10,000-lb trailer would have a tongue weight between 1,000 lbs and 1,500 lbs. For a trailer this size, you would need a jack with a lift capacity of at least 1,500 lbs.

It's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher lift capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.

Trailer and Camper Jack Lift

Every jack offers a certain amount of lift or travel. Screw travel is the distance the jack extends when you crank it (or toggle it to "extend" on an electric model). Some jacks include a drop leg for extra adjustability. On these jacks, you'll see the maximum extension of the drop leg listed in the specs as well. Adding the screw travel and drop leg travel together will give you the total lift. The total lift listed above can help you determine how high this jack will be able to raise your trailer.

Excellent Jack. Slow moving but that is due to high torque. Well made, attractive design. Highly recommended! Solved the problem of busting my knuckles on the propane tanks while cranking the old jack.

Great...no problems.

I received my new Bulldog jack fast after placing my order. It took me about 20 minutes to remove my old one and install the new one. This Bulldog jack is quieter than the previous one and moved up and down real well. I needed to hook up in the evening before I left for my camping trip and will say the nice led light this jack comes with gives a very nice lighting to be able to see everything needed to hook up my trailer to my truck. I hope this one lasts much longer than my previous one. Time will tell but so far I really like the way this Bulldog jack operates

- BD500187

Very happy with the performance of our Bulldog. The name fits. What a difference as compared to a manual jack. Well worth the modest expense, and installation was hardly rocket science. The built in light is a great feature for evening set ups. A minor tip - cover the motor during outside storage to limit the risk of water seepage into the unit. Our experience with etrailer was also very positive.

Our Bulldog performs like it just came ouu u t of the box. The Full Monty!

It's been a year now, and my jack is working just like it did a year ago when I installed it on my 32ft wildwood camper. Still smooth motion up and down. I really enjoy having it. Makes camping so much easier. One of the best purchase decisions I have made! I do have a cover I put on it when I bought it new, so it has never been wet, or exposed to sunlight. I can work the buttons on the jack through the cover, so I never take it off. I do love the jack. Thank you guys so much for good quality at a great great price!

Its been a year and still woring as good as day one. Love it!

Great product and easy install! Customer service great with placing order and follow up!

- BD500187

Fair price. Quick shipping. Arrived as promised.Installation video was very helpful, as were the instructions. Add the drop leg BEFORE bolting the unit in place. Otherwise, you need to raise the tongue to get the leg underneath. Simple install.

- BD500187

What a dream come true! This electric jack replaced my old hand crank unit on my 24 foot travel trailer. Installation was very simple with the one wire hook up. What I like most about this jack is the drop leg. This jack extends so far that now I won't need to bring all my boards (for lifting height) with me just to get the trailer off of the hitch. Not included was a ring terminal for attaching the wire to the battery, but thats okay because I had one laying around. Another thing that I did, was that I found some flat washers to use between the head of the mounting bolt and the jack. The provided lock washers looked like they'd pull through the mounting plate. Just be aware that the motor unit on the jack protrudes to the back and front of the center line of the jack tube. I'll have to deal with some clearance issues between the jack motor and my propane tanks. This isn't a flaw with the jack, just a quirk with my particular trailer setup. Its a very nicely built jack, feels solid and heavy in your hand. Its powerful too. It had no problem picking up the trailer and my 2007 F-150 in order to install my weight distributing bars.

If you need a ring terminal to wire this jack part # BD500187 I recommend part # DW05705-1
Ring Terminal - 12-10 Gauge Wire - 3/8" Ring ID
for a 3/8 stud size, part 44-5310A for a 3/16 stud size or part 44-5356A for a 5/16 stud size. All of these ring terminals will work with 12-10 Gauge Wire. Deka 10 gauge wire part # 10-1-1
10 Gauge Primary Wire - Blue - per Foot
will work well if you need extra wire.

Jack still working great after one year. Hooking up the trailer is so easy. I don’t Miss that old hand crank at all.

ordering and free delivery was nice, arrived in good condition, easy to install, justed installed and works well, beats raising and lowering trailer by hand, 26 ft enclosed trailer

- BD500187

The product came well packaged... on the second shipment! The first one was open and not good looking. Stuff happens, and it was corrected very quickly by etrailer reshipping a perfectly new Jack. And it works good and is really strong. Very happy with etrailer service and the Bulldog product.

After a year, product works as it should, I am very happy.

Quality is good, easy install. The ability to mount it 90 degrees is a plus.

The Bulldog Powered-Drive Trailer Jack - Drop Leg - A-Frame - 14" Lift - 3,500 lbs - Black was very quick and easy to install. Seems to work great. This is on a small 3700 lb travel trailer and lifts with ease. Need to determine how far to ext and retract as not to blow fuses but it works great so far. Can't wait to take it out and see how it performs camping.

Working great with no problems for a year

Jack arrived in 2 days. Fits great and easy to install. Jack head only sticks out 3 inches from front of tube, closer then most. This allows me to open tailgate without hitting jack. I use an extended reciever for more clearance. Light on jack also shines in the bed of truck.

Works great. No problems. Very nice jack.

Shipping was fast and amazing as always. This jack bolted right on to my 2019 175LHS Hideout with the supplied hardware. Wired right up. I am excited about the drop leg. Will be nice to not have to run the jack all day. So far grat stuff. Would highly recommend.

- BD500187

Great jack. I quickly found out that this jack also blows fuses if retracted completely, which is apparently common. It is a little slower than the Super Jack it replaced, but I like the added features such as: multiple mounting holes for mounting in different positions, LED lights, the switch is labeled up and down (my old jack wasn't, so if you were near the top and hit the switch the wrong way, you were replacing 20A fuses), and the adjustable drop leg. I am not crazy about the gold/bronze drop leg, but nothing a can of paint cant fix. I installed it in just a few minutes as it is simply three bolts and one electrical connection. I ordered the jack on Saturday and it was at my house on Tuesday with regular ground shipping. Further, I received constant email updates on where the shipping process was. Great service again from etrailer.

The blown fuses can happen when the motor is over-loaded either by over-extending or over-retracting the jacks. A helpful trick is to mark the leg at stop points with a paint pen or scratch tool. That way you know when the jack is all the way up or down and you do not go too far and blow the fuse.

I should say that I initially ordered a different unit that was substantially less money. Unfortunately that one was on back order, which i did not know at the time I placed the order. With that said I had researched this one and the reviews seemed good. Packaging upon receipt was not 100% intact. The unit itself seemed fine. Installation was easy up until the point of installing the leg/foot. I had to use a floor jack to lift the trailer high enough to install the extension leg. I can't see another option so be prepared with a jack and several heavy boards to get enough height for insertion. Be sure to clean the trailer location where the mounting base makes contact. This will help insure a good ground and without that good grounding surface the unit will not operate. Pros - Heavy duty feel. - Motor seems very strong. - No problem lifting truck and trailer high enough for WD hitch bar installation. - LED Lights are excellent. - Extension leg is very nice to work with, saves time during set up / break down. Cons - Price, I think this could be priced a little lower based upon features and competitive units of the same rating. - Slow...really slow. without the extension leg this would be a major negative. As it is its only an inconvenience. - Head size, doesn't allow tailgate of truck to open all the way.

I installed a new trailer jack on my 2016 Lance 22' Travel Trailer. The jack handles about 400-lb. greater capacity than the original equipment and works great with no hiccups. The problem is with the power or control head on the unit, which extends about 2' to the rear or toward the trailer, prevents use of the cover or shroud for the gas bottles. I don't like leaving the bottles, valves and hoses exposed to the elements and possible theft. Either the jack has to be moved forward or the bottles and their mounts have to be moved to the rear. Either way involves drilling new mounting holes in the platform - a major pain!

- BD500187

Excellent job of lifting, easy to use motor cover needs to be waterproof better. Forget the covered bag use a bucket. Other than the motor cover great piece of equipment.

- BD500187

Item arrived in a VERY torn and beat up original packaging box. I was afraid to open it and find a damaged jack, but the unit actually was in great shape. Installation was a snap and it works well. Good instruction manual was included. Easily lifts my 28' 8K pound trailer. It is a little slow, but I haven't seen a quick one, so no big deal. It is quiet compared to the one I replaced. I like that.

- BD500187

Great product. Saves time and effort to get the camper unhooked. Built well and went on the camper with no trouble. Also got much follow-up from ETrailer reminding me that if I did have issues, they were there to help me out. Thanks folks!!

Fantastic!! Saves my arms and back. Only problem I have had is why didnt I get this jack much sooner.

The jack has been great. Used it to replace the factory hand crank. Don't know if I can ever go back to a hand crank now. Two thumbs up.

Love this thing, it is so easy to use. I would recommend it to anyone!

One year review : Excellent. I bought a used camper. Toungue Jack failed immediately. I searched for a quality replacement jack and found this. It was easy to install ( i am disabled ) and has performed well and met my every expectation. I keep the head tightly covered with a plastic bag to protect from the elements, and also a vinyl slip on cover to protect from uv. I use this on a Rockwood 2109s camper.

- BD500187

Product received was as ordered. Installation was very easy. Mounted sideways as propane tank cover was in the way so this put the controls on the drivers side which will be handier for me. Took longer to decide how I wanted to wire than to install. Jack is very capable, smooth and quite. Installed on 22 foot camper. Tongue weight of aprox. 360 pounds. Have not used to hook up to truck to install leveling bars yet, but should work O.K. given it is rated for 3500 lbs.

- BD500187

I ordered the Bulldog trailer tongue Jack last week and it was delivered on time Thursday 21 September. I liked the ease of installation and how quiet it is to operate. Now I won't have to crank my trailer tongue up and down by hand to get the spring bars installed. Thank you for a great product.

- BD500187

The Bulldog camper Jack works great. I would recommend this to anyone who needs to replace their old one. E-trailer customer service, is very knowledgeable and very helpful I would recommend e-trailer for all of your camping needs.
