Billyray,
I didn't have to add the supports for the tank. I just wanted to so when I drain the tank I didn't have 3 or 4 gallons still in the tank due to the polyethylene sagging / stretching from weight.
And Yes, you can put water in the tank with it off the truck. I did have some of the frames with cracked welds (previous post last year) but it's an 05' and don't know how many miles were on it.
I've got about 8K miles on it with no issues except a frig fan and those darn bugs on the front.
Bobndot,
Yes, you can buy a TC that has a problem due to mfg defect. But It's a machine that goes down the road. Things can deteriorate if maintenance isn't done. I read the posts you attached, but what I noted was that the OP had his TC 5 years and didn't mention maintenance. After the first year you have to take care of it or pay for it which ever suits the owner.
All but 1 RV that I've bought had issues. I look at the unit and assess what it needs and offer what I think it's worth. I've bought 2 knowing they had roof leaks. Even if it is new, I go over the unit and rework it to my standards.
I've replaced roofs, front caps, floors, framing, aluminum, and fiberglass. If I get to the point I can't take care of my toys I'll change hobbies.
So far, I only squeal and grunt when getting up off the floor.
The glass needs to be half full when you deal with RV. If it breaks, I whine about it to the wife, but in the end it's just another opportunity to excel.
