I'm planning on buying & installing the 4 point system at the pre-rally. I've been calling Lippert to make sure I've got the right tools with me. I'd hate to have to go out & buy something at the rally that I've got at home. I've called them 3 times now, & no one can answer my questions, & they say they'll find out & call me back. Guess they never found out as I've never been called.
If it's the same as the original 4-jack system, you'll need a good drill with bits. A corded drill might be a better choice, but a strong cordless will get it. A socket set and box wrenches is also a good thing. Although my set came with self-tapping bolts to attach the jack mounts to the frame, I opted to replace them with Grade 8 zinc dichromated bolts, washers and nuts. I drilled through the frame web and attached them. I found the ASTM A307 bolts they supplied with the system were not rated for the torques they called for in the instructions. Fortunately, I found that out quickly after snapping the first one before even getting near the torque value.
The electrical connections are all plug together, so you don't have to worry about splicing and wire nuts. You will need to drop the coroplast along one side to run the wires from the rear jacks to the controller. Working by myself in a storage yard (10 miles from home), it took me two days to put them on. That included having to run up to a fastener supplier to get the proper bolts for it. Fortunately, the front jacks were no problem since I don't have a generator. I used my cribbing blocks to support the front end after lifting the rig.
