Definitely worth doing your homework with FR first. Not sure where they'd stand in regards to roof warranty. I'm sure if they did it, it wouldn't be an issue, but that'd be a drive. I'm probably a little too confident in some parts of an RV, as we've voided many a frame warranty and probably some other warranties with mods we've done. I guess I figured if it broke, I'd end up fixing it myself anyway. I know FR will approve work at many places, so it'd be worth checking it out. If you decide to have it installed, I'd love to see some pictures.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
