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.

Product fit and function was perfect. Customer service prior to order was great making sure product would fit my jacks.
!st off I believe the Happi Jack products are top quality, BUT!!!! when you pay 1500.00 bucks for something you expect INSTRUCTIONS! and their are basically none.
So what questions are not answered...
1. the new circuit board has places for all for Jacks it says on it front right front left etc BUT which way do you look at the camper from the back or front?(would be nice to know).
2. do you leave the extra wire left from wiring and just coil it up in battery compartment or can you cut the wires making them all different lengths will this effect current draw?
3. what size hole do you drill in the side of your camper to fit the little boxes in I don't like redrilling holes because the first time is the wrong size!
4.why is their no wires for connection to battery? Ok so now I need to make them what size wire? does it get a inline fuse on the hot side? what size? NO? is it built into the circuit board?
So this is why I am giving it a average rating spend a dollar and make a great detailed instruction book ,doing a install job and having the answers to your questions make the job fun and less time consuming and most of all less frustrating....

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.

Arrived on time and worked as expected. Very pleased with the customer service and the jacks.
After a few issues with my order ( by the manufacturer not etrailer ? ) getting all the parts delivered ...etrailer went above and beyond to correct this issue - Now I have received everything I ordered and it's correct ! Admittedly this was a headache , and I really did not care who's error it was , at least I know that etrailer came through to make it right - excellent service
Added this conversion kit to my 2007 truck camper, everything worked perfectly! You definitely need to be prepared to do some work running the wires if your camper is not pre-wired - but everything necessary is included and works as it should. It still works perfectly one year later, and at least 20 loading and unloading cycles.
very pleased with the jacks once I got them installed, would have given an excellent rating but I think more detailed installation instructions would have been a plus
Thanks for the great product and for the fast delivery!
quick delivery! Will shop here again.
