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 10000-lb trailer would have a tongue weight between 1000 lbs and 1500 lbs. For a trailer this size you would need a jack with a lift capacity of at least 1500 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.
