Hi, We have a 2002 Coleman Utah that we love. When I bought it I knew the floor in the storage box was rotten and I am considering replacing the entire floor. I've watched several videos and think I can handle the work, I'm wondering if anyone has done this on this model, or one with a slide? Also the rear panel seems to be a little loose. I'd like to rebuild the back wall, but I'm not sure how to go about doing that. Ultimately we are hoping to get it the camper nice and solid and do a renovation. Any info is appreciated. Thanks.
