We are totally new to Rv's, so any advice would be greatly appreciated. Here goes! We are about to buy a '91 Winnebago Warrior, 23' with 73k miles on it. It was purchased new in '91 and has stayed in the same family for 26 yrs. The only reason it's being sold is the fellow wants a new fifth wheel. He is the head mechanic at my husband's bus garage. It has all of the maintenance records and is really in excellent condition for its age. This being said, I did notice two small areas on the wall where at one time was a small leak. I pushed on these spots and there is no softness or erosion that I could tell, just the wallpaper was a touch bubbled. We checked the outside and everything is sealed and intact. He told us that years ago, there was a small leak but it was fixed right away. I tend to believe him, considering this unit has been so well taken care of. I had read articles that said, "if you see water damage steer clear!" Do you think this is something that we should worry about?
