Hello all, I recently purchased a 1998 Coleman Rio pop up, and unfortunately I believe the lift drive shaft became stripped while we were cleaning/repairing the camper (got stuck up, can manually grip the drive shaft and bring it up/down). I've yet to take the whole thing apart to confirm the damage, but wondering if anyone had any advice on what I should look for outside of the driveshaft. I'm going to put it off until the spring for the time being, as it's nearly ready to store for winter, but I'm thinking at a minimum I might need to inspect the wiffle tree to see if something is binding in there or needs to be greased. To note, it did take a bit of effort to bring it fully up prior to the mechanism breaking, so I suspect it might need some maintenance. This is my first pop up, so any insight would be greatly appreciated!
