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.

I am extremely pleased with everything about the purchase. The jack was described very accurately, I had a question before delivery about the fit on my R-Pod which was answered very thoroughly and the jack arrived on time. The installation was quick and easy. The jack operates very smoothly. The features of the LEDs, the quick pull pin for the drop foot and the bubble level are perfect for my application.

I installed this electric jack on my 3-horse bumper pull trailer. I'm using power straight from the truck's RV 7 wire hook-up. I, along with my family are so glad I installed this every time we hook up to the trailer. The adjustable leg is also an added benefit. I also purchased the termination box and this allowed for a superior installation by putting all the terminations in a water proof box versus open wire joints. Thanks etrailer for your support and your quality products.

Still lifting and lowering my trailer as designed. Having used the jack up to 6-8 times a month, I is withstanding the rigors of hauling. The little bubble level on top of the jack is pretty much useless in my application besides, the bubble is now about the length of the vial. Short of that, Id recommend to others. I am please with this product and sometimes wonder if I should have purchased the next size up.

I purchase this item to replace a 12 year old power jack. I’m spoiled and I’ll never go back to a manual jack. The jack feels and looks like a high-quality unit. All hardware was individual packaged. Installation went smoothly following the excellent directions. I’ve run the jack up and down a couple of times and it functions smoothly and quietly. The drop-leg is an excellent design. I look forward to many years of service from this jack.

I have found a flaw in the jack. The metal rod used to release the foot is made from pretty junky metal. It got hung-up in my chains while I was lowering the jack and bent. The deflection was pretty minimal - I caught it very quickly - yet when I bent the long leg of the rod back, it broke off. For the price, I’m not impressed with this aspect of the jack. It has rendered the [] leg useless as I had to secure it in place so it didn’t fall out.

The Bulldog Powered Trailer Jack was a perfect fit for my Jayco White Hawk travel trailer. Installation was easy and the switches are easy to operate and are clearly marked. The customer service reps were awesome!

- BD500200

Easy to install, works well. Used it to replace another jack that died after 5 years. It would be good if they included the electric hook up instructions with it. If I didn’t have the earlier jack connections I would have had a much more difficult time installing.

I have a 2007 14' V-noise extra wide and tall trailer, and the jack was needing to be replaced. I figured it was a good time to think about a powered lift option. After spending several days doing research, I determined that the Bulldog Powered Drive Trailer Jack, was the best product to meet my needs. etrailer has this product for the best price online, and offered free shipping, so for basically $100 more than a high quality none powered replacement jack, It was a no-brainer. My wife and I installed the unit on my trailer that was still on my tow vehicle in less than 45 minutes, and everything we needed minus a weather proof inline connector was included. It was so easy to install, and looked so good after installation. Because of the size and weight of my trailer, hooking and unhooking my trailer used to be a real chore for me, since I am older and have back problems. Then it was time for the true test, dropping the trailer for the first time. WOW! The spring loaded pin for the drop leg made it so easy! No more need for the several wood blocks we needed to lug around. Also it was now dark, so I turned on the lights. What a difference! The video does not do the lights justice. They clearly illuminate the rear of the tow vehicle, and front of the A-frame of the trailer. Then, by simply pushing the weather proof button, a chore I used to dread, that left me sore and sweaty, was now effortless! Quiet, smooth operation, and built in stops for extra protection. Very solid high quality construction, with all the features you need and want. The all weather design, powder coated metal parts make it easy to understand the reason why the manufacturer offer a 5-year warranty. I am only left with one question...why did I wait so long to buy this great product at the lowest price from Etrailer?

great product the package was in bad shape when delivered by UPS hope everything is there.

- BD500200

Quick easy installation, all hardware provided, lights are just enough to see what your doing, only reason it's not 5 stars is because I've used it long enough to test. But it will be used daily, so testing won't take long, oh by the way shipping was 10 stars, haven't had a package arrive like it was supposed to in long time. Thanks everyone involved etrailer!

Review from a similar Powered Drive Trailer Jack in Camper Jacks

Bulldog BD500199 installed on 2006 Jayco Jayflight 27BH. Bought this powered jack to replace the non-functioning electric jack that came with the camper we bought 6mo ago. We’ve been using the manual override on the old one, so having a working jack is going to be great:) Just installed this new unit yesterday, so have only used at home so far, but it seems to work very well. Speed is good. It has the drop leg with spring pin for quick adjustment which is cool. It has a built in light which is fairly bright and should come in handy for setting up at night. Installation was very easy. Literally had the old jack removed and new one in place in about 20mins and that included getting the jack stands set up. The hole in the A-frame was big enough for the larger diameter tube of the Bulldog unit, so no fitment problems. I’ve got photos showing the old unit and new. Forgot to take one with the jack removed. There was additional time wiring, but it was only another 20mins or so. Most of that time was spent deciding on routing and zip tying the wire. There is only one wire that hooks up to the battery positive post and there is an internal breaker in the unit so you don’t wire in an external fuse. Heads up there are no wire terminals in the kit, so you will need to have your own to crimp onto the wire. You’ll need a 10ga connector, likely a 5/16 or 3/8 ring terminal but could vary depending on your battery. The wire lead could have been another 12” longer, but it was just barely long enough to reach the positive post after I flipped the battery around to put the positive post on that side of the frame. Also should note that this unit has a dual mounting pattern that allows for turning the head unit 90deg to face sideways, which is what I ended up doing. Facing forward, the head of the jack was really tight up against the propane bottles/cover, so turning it sideways fit much better with our camper. Looks to be well built, so hoping it lasts a long time, and I’m looking forward to not using a manual override crank next time we go camping!

Review from a similar Powered Drive Trailer Jack in Camper Jacks

I just installed this unit. It was so simple and easy to install. It took about 30 min ( minus the 2 hr it took to grind out 20 year old bolts from the manual jack). I love the sleek look of the unit. Gave it a test run and it's so quiet. I have a bumper pull horse trailer with a small living quarters and it lifted and retracted with no issues. Very happy with this product.
