I installed this power jack on my KZ single axle travel trailer. It was very easy to install. I hooked the trailer to my truck to support the tongue, removed the manual jack, bolted in the Husky jack, and wired it into the trailer battery system. For the power hookup, I used a large alligator clip from the auto supply store, so the jack is not powered unless I connect the alligator clip to the battery. That gives some piece of mind that the lights can't be left on inadvertently or the unit activated by an unauthorized person.The lights are not very bright but nonetheless very helpful when working in the dark. I especially like the slip joint and pin on the pad foot, so the foot can be dropped as low as possible when disconnecting from the tow vehicle. This saves a lot of cranking and wear and tear and extends the usable lift height on sloped parking pads.I would like to see the unit a bit stiffer in the later direction. Any tongue jack has problems with the trailer shifting while lifting or dropping. My solution is the put some tension on the trailer chocks when disconnecting so there is no play when jacking the trailer, which keeps lateral forced from building on the jack.This isn't a fast device but it's still faster than manual cranking a hand operated tongue jack. There is a manual crank system if your battery goes dead.This power jack makes setting up and tearing down the campsite much easier, and I'm glad I added it to my RV.
