We had a 26' Class C for a couple of seasons. It was something of an orphan. Ours was a Winnebago version, but we found out later that the model had been a Winnie for only about 9 months of its production life. They sold the design off to another manufacturer.
We bought it to "see if we liked RVing". We did, but that thing was a turkey, mainly because of its odd-ball layout and equipment. It was a 198-something with a carb equipped Ford 460. Enough anti-smog gear to get the space shuttle a street license and 5 mpg (average) at sea level.
On the plus side, we never had any problems with water ingress. It was a very solidly built rig, rectangular steel-tube body frame with aluminum skin. We managed to sell it through a local dealer's consignment plan and didn't lose too much from our original purchase price.
Subsequently, we bought a 32' Class A, which we used for four seasons before giving up the RV life.
