I was given (for free) a 1988 22' Viking Pop camper with fold - a - sides & the Heco EZ lift system. The camper appeared to be in pretty decent shape considering the age. The issue was that all four pivot points on the lift system were broken or badly bent and close to breaking. I went online and found that the repair kits were readily available , but @ $100.00 a piece, I wanted to make sure the camper was decent on the inside before i made that kind of investment. Me and 3 other burly men maneuvered the top up and secured it with the existing arms, and placed heavy pipe on the upper and lower arms to hold it in place. Everything looked great! I found that the AC in the roof had been removed and replaced with a window unit in the front over the tongue. I replaced that, with a bigger new one, and ordered the repair arm kits for the lift system. The parts arrived, and per instructions, I carefully held the old arms up, and marked and cut them to receive the new repair parts. I used bolts to secure the repair sleeve, and everything looked great! I went to lift it up with me and my brother in law, and the thing was so heavy we could barely lift it up. We checked the springs, and all appear to be pretty tight in the closed position. When you undo the latches though all four corners pop up free but stop at different heights. It took 4 folks to lift the thing up again, and now, on the fold a walls are not lining up on the roof gasket at the top along the cent portion of the wall. When you go to let it down, not only is it hard to slide the sleeves, but when all are up, the damn thing comes flying down like a rocket, and will eventually hurt someone, or break something. Does anyone understand the adjustments or operation on this type of lift system? I am certain, a series of adjustments could possibly correct this, but at this point I am not sure. PLEASE HELP!!!!!
