I drank the koolaid myself. Tiffin has a cult like following even though Tiffin's have more problems than any other manufacturer. I wouldn't buy another one. They have re-designed their roof three times over the past few years using their customers as their guinea pigs. The big three repairs that Tiffin's have required are: Rotting wet bay floors, Roof rail separation and Drivers side floor problems. They kept pumping them out even though they hadn't solved the problems yet. I found their general quality controls very poor also.
The positive things about Tiffin's in my opinion are that they offer a lot for your money, they have great designs inside and out and they stand behind their product and are known to have even fixed things that were out of warranty.
