lass A's can be more stressful on ya if in tight situations. They are higher for the driver thus you may miss closeup, they have a big blind spot on the passenger side and then take more room to maneuver overall. I drive a school bus and dont find the idea of driving a big bus for pleasure fu, We bought a Winnebago B+, it is just like a small school bus thus our name for it and it is actually easier to park and stow away when not needed. It is only 11ft high an I can get a storage shed for it cheaper than for a taller A. Its only me and the wife, it does have seat belts for more in the back but grand kids too small to take with us no so its not an issue. Yo need to do as recommended above, rent 1 of each and see which makes you feel more comfortable. Remember in an A the steer wheels are under your butt and in a C they are in a normal drive position.
Have fun however you go.
