Gotta say.... while I can appreciate the personal attachment you have for your
Trillium, having to farm out repairs can quickly become money pit for you.
Almost anyone that works on RV's in general can do
about 90% of most repairs needed on FGRV,s, one doesn't need to be a Trillium specialist
I have done FGRV repairs/restoration at both a local dealer ($125/ hr.) and in my driveway ($25-50/hr depending on attitude) and even the smallest repairs can quickly add up.
For example:
Complete rewire: $400 - $800+ parts
Repaint: $1200+bodywork + material
Remove and reseal
windows & bellyband $400 (unless done with repaint)
Bottom Line: Unless you can do your own work, it is usually far less expensive to buy a better FGRV than to do extensive repair/restoration work on a project trailer. There are a lot of buyers out there, who can do their own work, that will jump at the chance to buy your Trillium. That, and less money than your restoration will cost, will result in a trailer in better condition that you can use now, not later.
In either case, good luck
