So who else has the same problem as me? I go in to a project expecting to fix something simple, in this case it was repairing a couple of latches on the storage box. By evening the storage box was completely ripped off, toilet/shower and half the back end of the camper removed lol So basically last camping trip I had a SPUT. 2 latches on the storage box weren't working, so I just bungeed the box down and tightened up the other 2. Only I forgot to latch the other 2! The wind got a hold of it and just ripped up the ABS lid. Ugh. So I was going to build a new lid. I knew there was some water damage on the floor under the storage box when I bought the camper, which is common for this model, but as I was investigating and it was bad. I figured it's winter let's go ahead and knock this out now. Went ahead and booked a trip in March to keep myself motivated! I'll keep this thread updated with pictures as I go along. The current plan is to take out about 2 feet of bad wood from the floor, replace it, rebuild the shelf unit and seal off the front of the camper. I'm getting rid of the storage box and I'm going to but a cargo carrier in front (I already have an old one I figured I would use it instead of buying a toolbox). I'll also mount a few waterproof smaller toolboxes somewhere. First question: What kind of plywood should I buy to use on the flooring? My first thought was treated plywood but I seem to recall reading somewhere that you don't want to use treated wood that will be in contact with the steel frame. Any suggestions?
