I do not own a class A yet, I have a TC, but looking pretty close to get one.
I would like a Class A for:
Big windshield, no view restriction while driving or parked
Do not have to get out of the truck to go in the RV, especially when it rains
The RV is already warm, or cold when we stop for the night
Do not need to get out to go to toilet
Prefer A to C because there is no overhead blocking the view
Very quick to set up when boonducking
The down side:
Expensive RV and could be more expensive repairs
Poor MPG
Own Maintenance: cannot get into the garage, need big tools,
Cannot get to all the places I go with the TC, size is important
Would like 30 foot or less for camping in any park, smaller than 30, it normaly does not have a sofa
Harder to keep cold in hot temp or warm when near or below freezing out temp.
