Hi! A few weekends ago there was a pop up for sale across the street from us... we went and looked at it and it was like fate! The canvas had mildew but we didn't see any holes (esp compared to the last one we were looking at!) and everything looked to be in good shape. I checked out the inside, my hubby walked around the outside. We looked under the camper for water damage and I looked at the roof inside for water damage. It seemed that maybe it was put down wet at some point and not put back up to dry out... at least the amount of mildew on the tenting would indicate that. It is a 97 Viking Epic 1706. We bought it! Our neighbor helped us pull it pull it home (as we don't have a hitch yet...LOL!) and we popped it up in our driveway right away! We were soooo excited! I got started cleaning the inside up... I researched how to clean the mildew and I have a good handle on that. The side I have cleaned looks brand new! Hooray! We replaced the cover for our electric plug as the little flap door was gone and we wanted to protect from bugs... no problems replacing that. When we put it down the first time though we started to notice some things. On one bunk end it appears the wood on the side roof had been wet at one point. It is still solid just stained... so we were not to worried about that.... my hubby went around the area on the outside with some new silicone calk (please tell me that was the right kind to use!!!) to be sure it was all sealed good. However, it was when we had it all the way down and we were locking up the back right corner (the non door side) that I noticed when I put the latch over the lip the lip pulled down and looked as if it was trying to pull out of the side. We pushed on that roof side and sure enough it is REALLY soft compared to the rest of the camper... which is not soft at all. We can't see the actual wood at all because when we look under next to the tenting it has like white wallpaper over it. But goodness we are worried. It is soft from the corner where it latches just to the lift arm.... So not much of it... but enough to have me pretty worried. Any suggestions on how to fix it without taking the roof off or redoing the whole thing? Can we just add a piece of wood behind somehow? We can diy a lot but this kind of scares us. I have some pictures but can not seem to figure out how to add them now... I will keep trying to post them below. Thanks for ANY help!
