Install and remove your truck bed camper faster and easier than ever with this manual-to-electric conversion kit. Includes everything you need to upgrade your existing HappiJac jacks and eliminate the need for manual cranking.
Features:
Lifting your truck camper on and off your pickup truck is challenging and tedious if you don't have the right equipment. This manual-to-electric conversion kit includes everything you need to upgrade your existing manual HappiJac truck camper jack system so you can load and unload your camper with ease.
Unlike manual jacks, electric jacks make it easy to mount or remove your camper on your own. There's no need to rely on someone else to operate the jacks on one side while you crank on the other to ensure the necessary incremental adjustments. And if you normally do this on your own, then you'll save a ton of time not having to bounce from side to side.
A user-friendly, wireless remote control is included to operate these jacks. This gives you the freedom to stand back while lifting and lowering so you can make sure that you're keeping your camper level every step of the way.
The remote lets you extend and retract each jack individually or simultaneously. And it is conveniently labeled and color-coded for simple operation.
The circuit board mounts vertically inside your camper, near the front bed wall, typically by the main electrical panel. The motor heads replace the plastic caps on each of your existing jacks and secure with the included hardware. The included wiring harnesses connect each jack motor head to the circuit board.

I am sorry to hear about your experience with the instructions on this Happijac system. I have gone ahead and attached a few instruction manuals for this kit to get a better idea on the installation. Please let me know if you still have questions after looking at these and I can keep digging into it for you.

I am sorry to hear that is not in the instructions James. I did a little research; To reset the Lippert/HappiJac electric jack system after a timeout, disconnect power to the unit (either by removing the camper battery connection or pulling the fuse), wait about 30–60 seconds, then restore power and try again. If you’re using a wireless remote, you can also remove its batteries for about 30 seconds and reinstall them. This reset clears the controller if it shut down due to inactivity, low voltage, or overload.
