Thanks, but, besides the leaking, the mildew stains on the foam are the biggest reason for me to do the replacement. Otherwise, I doubt I'd ever get my wife to come out with me.
Silicone is great, but over time it seems to lose it's adhesive to aluminum. I found a sealant called Duralink, this stuff really sticks. I think this will last much longer than silicone. I'll be using that when it goes back together.
FWC wants $995 for replacement canvas, or $1700 to do the job. So, I'm going to a local upholstery shop for a quote to sew it up. I'm thinking of having velcro sewn around both the top and bottom, and making it removable.
The roof has a tweek where a previous owner started to open the camper with one of the latches still closed. So while I have it apart I can address that, run my wiring for the fantastic vent and replace the ceiling material also.
...I hope I get it all done while I still can climb into it!
