I have owned four motorhomes, three Class As and one Class C.
The first Class A was on a Dodge chassis, 440 engine. I loved the engine, hated the floor plan.
So, we got a larger Class A on a GM chassis. I loved the floor plan, hated the 454 engine. It was a carbureted gutless gas hog.
Then we got the Class C, on a Ford E350 chassis, 460 engine. Nice floor plan, adequate power, and "it figures" fuel economy. But, there was the exhaust manifold problem.
Now, we have a Class A on the F53 chassis, V10, single slide out, good floor plan. I think we will have this one until I die. I like everything about it (except the fuel economy, but, hey, it is a 32 foot motorhome!)
I agree with Pirate...
