After many years, I'm still working on my 13' 1981
Burro.
I recently completed (translation: recovered from the PTSD associated with) an off-frame floor replacement that I started 4-5 years ago and now I'm taking care of what's left.
I'm installing a Fantastic Fan. The problem is the curve of the roof. When I lay the fan into the hole I've got about a 2" difference in the roof-to-flange distance between the inner and outer sides. While the thinner, inner side of the hole will "give", I don't think I can expect it to move upwards that much when I screw the fan down into it.
I'm considering making a contoured support, that would go on top of the roof, to accomodate the discrepancy but wanted to see what other folk's experiences have been.
I don't know if this problem is universal to all Molded
Fiberglass RVs, only to those with vertical seams, only to Burros or only to
my Burro, but figured I'd toss the question out there. I appreciate the assistance.
