I don’t know what some of the above are talking about, really. I have had two TT, class A, a 28’ class C and now a 29’ class C. The 28’ was a Ford based unit. The 29’ is a Chevy based unit with a much better road manners stock. Plus I can get out of the driver’s seat into the MH with ease. Also more mpg.
Both have had rear bedrooms. The first one had a bunk over the cab. Great for the grandkid when not used as storage. The current one has an “entertainment console” that has the same storage behind the TV I had last time. A win, win I think.
The overhead storage also blocks the sun when driving. More so when going south. I think that is a big plus.
It all boils down to the floor plan you like, really.
If you want tips here is what I have found works for me.
Things to look for I have found value in while having in a class C ….
Walk into shower. Some showers you have to step up to get into them.
Corner shower, some are bigger than others. Big ones are real roomy inside.
Counter space by the kitchen sink for food prep.
Large outside rear storage. They can be up to 100cu ft.
No window over the headboard of the bed.
Livable with slide(s) in.
A north south bed that is offset to one side. That gives you room to walk & dress on one side.
60x80 real queen bed. Uses standard bed sheets and such.
Ford E450 or Chevy 4500 chassis. As a Ford guy, I have found the Chevy better. Hate to admit that.
Just a comment. All class Cs have an overhead above the cab designed to be a bed or audio center. It is a great place for storing things.
