We found the trailer jack broken when we picked up the new pop up camper. It was there but the welds were all snapped off. The front of the trailer was sitting on blocks. Lucky these trailers are light enough to pick up and put on the hitch ball.
The first thing we did when we got the pop up home, was run to our local Harbor Freight for a trailer jack. We got the Haul-Master swing-away trailer jack with a 1000lb capacity.
This jack is easy to install. It only bolts onto a trailer frame with four bolts. First decide what set of holes to use. There are multiple options to fit different frames. The hardest part is holding the jack while starting the nuts.
I mounted the jack right in front of the weld of the original jack.
After a few minutes, we had a working trailer jack again, and it was easy to move the camper around.
Happy Camping
