As promised in introduction, we have just purchased a 2010 rock wood 1460 LTD pop up. It appeared to be over all in very good condition. All was solid, ceiling, sides and floor, beautiful interior in impeccable condition all features worked, canvas was flawless and fiberglass was glossy. I'd been looking for a small pop up to camp in again, and this seemed perfect for the 2 of us. I was a sucker for the nice interior; upholstery, floor and layout, heated mattress, nice clean fridge that worked great and the furnace which was quiet and warm. The sink had never been used and all the paperwork was tucked into the original envelope under the counter. I pressed on all the areas of the ceiling and sides, and they seemed very solid. I asked for the top to be put down, and that's when I should have walked away, but I didn't. It was clear something was the matter, there appeared to be some slightly low spots and signs that water had pooled. but I felt all the sides and top every where and there didn't seem to be any soft spots, so after a bit of haggling and some wishful thinking that there was nothing seriously wrong with the top, I bought it for $3500. I should say that I live in the southwest, and a new camper in such good condition is seldom that inexpensive. I still haven't seen one that I would rather have, if it hadn't had the roof problem. My husband was on board with the camper, and removed the calking from the neglected seams. 1st red flag, there were a lot of them. second red flag, the front side board had some rotten wood, which I missed when pushing on the surfaces. he applied a wood patch to the spot. He did a beautiful job resealing all the seams and we put it up to pack it. That night there was a good rain, almost all night. The slight dip in the front area of the top became a bigger dip and the top begin to leak very badly, all along the center interior seam, the interior ceiling dipping down as well. Right now it is set up, drying out and we have the low spot lifted with a support pole so that maybe the top will dry out in a slightly convex position. I sent photos to rock wood and they said it was delaminated and needs a new top. well, we can't afford that and now are forced to fix it ourselves and I'd like to ask for advice. basically my questions are-- I've tried to find out how the top is constructed, so we know where to safely brace the top from the inside, if necessary. the email from rock wood said: "It’s a laminated roof. Its fiberglass/luan on the outside, then aluminum framing and inside ceiling vacuumed bonded. Its 1 piece." which tells us nothing really about how best to brace it, if needed. do we have to brace it? does the fiberglass skin on this camper top ever become worn enough to be leaky all over or is it only possible to leak from a seam or crack we missed sealing? what would be the best product to seal this fiberglass "skin" that covers whatever the top is made of? Thank you so much in advance for any and all advice.
