Hello Everyone,
Thanks so much for the words of wisdom, I have been redoing a 2004 fleetwood wilderness 25' bumper pull, totally removed everything off roof and replaced and removed and redid caulking, used dicor for everything, removed everything from all sides, buffed, compounded and waxed everything and replaced inside and out every light with leds, along with a ton of other stuff the last 5 weeks so I have a pretty good idea but going to one like this with a diesel engine just a bit more involved to say the least,i have an uncle about 30 min away who is a retired diesel mechanic so going to pick his brain, the people who had it bought it to tailgate for their college football team and parked it during the season and paid to leave it set up, they had everything completely done when they got it and said if they have put 2000 miles on it that would be on the high side.
I do ceramic tile and corian counter tops for a living so have full shop to do most anything for it
