DW and I spend 3-5 months a year in our 32' A like OP plans to.
We've had an 18' C, 28' C, and now a 32' A (22000#)
What I noticed going from the C to A:
Cab space in A is usable so going from 28'C to 32'A we gained about 9-10' interior space, not just the additional 4'
A has pass through garage and holds so much more
22.5" tires are expensive but carry a LOT of stuff!
Front window is panorama on the A versus covered up and lower on C
If I were looking at 32' A vs C, would not consider C again.
hope that helps
we tow less than 5000# so super C is not necessary
