All houses on wheels have issues. Charles Kuralt said this in his book 25 years ago. And that is my experience. The key is to avoid ones that disable your motorhome in a major and possibly unfixable way. So expanding on this thread on Tiffin and Winny. If you like Winnebagos make sure you look carefully that there is not rust under it. And with Tiffins, don't get one with the problems talked about in this thread.
We own a brand that almost everyone says is one of the very best. We have nearly the top model from that maker. We bought a year that was referred to as a prime year. And we still have lots of repairs. Last week I coughed up 8 grand to CAT for a blown turbo intercooler, properly mounting the turbo another repair shop did not do right, cleaning out our radiator, and a tune up of valves on our CAT C12. When finished our 40,000 lb coach and Jeep tow car literally flew up the very steep grapevine going south. I think the CAT dealer left Superman hidden in the engine compartment. We were accelerating up a 6% grade in 4 with medium throttle. The computer said all 505 hp were alive and well in the back. And BTW we flew past an newer Allegro Bus struggling at about 40 mph on the grade. I guess he did not buy the upgraded motor from Tiffin and stuck with the basic.
One of our close friends bought a 1998 Winnebago 34' DP with 85,000 miles on it five years ago in Oregon. They enjoyed it and drove the c$#p out of it for four hears and had very few problems. When he sold it a year ago he had buyers literally lined up and sold it in two days for more than he paid. I did not ask him about rust, but they loved their W.
Tiffin as far as I know is the top selling class A maker. They must be doing something right then. Lots! of people like and buy Phaetons and other Tiffin models. And Alabama is a nice State to visit. Orange Beach is a great place. So is Mobile. If you get a Tiffin and have issues explore AL. There is a great battleship in the harbor and a fantastic seafood place next to it.
If you don't like doing mechanical repairs don't get a class A. You can separate the men from the boys by the size of their toys. And I still think the floor plan is very important.
