Sagging floor repairs
Last winter after installing the HPL flooring in my camper I noticed that there was slightly more "curve" to the floor of the camper when it is on the truck (read: hanging off the back) compared to when it is standing on its jacks... It's just enough to make the floating HPL boards lift up form the subfloor. I have heard rumors form a former Alpenlite dealer about floor issues with their TC's and it occurred to me that all the flexing can't be good for the camper in the long run so I decided to see what could be done about it.
I have some access to the basement and could see that the floor joists are only made from 1/4" luan ply and 1X2's that are stapled together :M . My solution was to cut a pair of doublers from a sheet of 1/2" birch ply and have my trusty pint-sized apprentice attach them to the existing joists on each side of the basement storage area. They are fastened with construction adhesive and cabinet screws.
Standing inside the camper the floor definitely feels firmer underfoot. I haven't loaded the camper back onto the truck yet so i don't know how much this will reduce the sag... but it certainly won't hurt.

This is what the stock joists looked like.
