I'll give these a shot
1 - are you anywhere near Atlanta?
2 - Slightly noisier and I'd say more comfy since they have less sway than a class A.
3 - Seriously doubt it.
4 - Not getting the conversion? Dunno, I've got a bunch to sway people the other way but really don't know what the draw of a regular RV is so I can't help you there sorry.
