jerem--I think this shop is the best shop in town. I checked with an RV place and they referred me directly to them. They would have sent it to him to do.
I will call the suggested place Monday. I checked their website and it really doesn't seem like work they do. I'm guessing they would send it out to the same guy.
I don't think it was outside his skill set. The gas tank, bins, plumbing all got in the way. They would have had to add a lot of weight to the back end.
Sometimes, things just can't be done safely.
