I have had two TT, one class A and now two class C motorhomes.
The first class C was on a Ford E350. This one is on a Chevy 4500. The stock Chevy 4500 does not get moved by big rigs passing. Crosswinds have to get into the 40mph range before you need two hands on the wheel.
Both class Cs had & have lots of storage inside & out. All the essentials from the class A fit into the class C.
My current Class C has a great floorplan for two. Even with the slide in that I almost never use. It has a 60x80 bed. The bed is offset so there is lots of walking room on one side. The larger of the two corner walk into showers was used. A four foot kitchen counter. A sofa bed with a dinette across on the curb side. Good insulation for when it is hot or cold. Most, if not all, interior panel seems are caulked. Lots of storage behind the entertainment center in the short cab over.
I really like the ability to get from the driver’s seat back into the house with no fuss. I have size 13 shoes and old legs.
