The only problem with my camper at the moment is related to lifting it. I didn't by electric jacks because they were $3,500 and I decided to use manual jacks instead. I was able to use a drill to raise the camper quicker but the problem was that doing it one at a time would cause the camper to lean. So I started having my wife help and that improved it but was still a problem. I then used cross bracing and again, that improved it but not enough. So, I decided to build my own electric jacks.
So this pic shows the cross bracing. I could have added more but I had to store the bracing and I was running out of room. So I decided to not add extra bracing.
The first thing I did was order a motor that I could connect to the jack and see if it was strong enough to raise the camper. I added a connector on the wiring, covered it, and made attachments to connect the motor to the jack. I tried the jack at all four corners to ensure it could lift the camper and it did it with ease. After completing that test I was full bore on finishing the project before the fall camping season began.
So I started building a control box with the wiring to connect to the four motors. I was keeping all of it external to the camper.
I mounted the motors on all the jacks and gave it a test.
Running the system on a 12v battery worked but it definitely taxed the battery so I attached a charger to keep the voltage up.
Other than how slow it is the system works great. I was able to build my own electric jacks for about $1,675 and even better than that, is it is infinitely safer.
