Where and how you will use your next RV will determine which is the better choice. The more info you share the more good input you will receive. What are you plans both short and long term? On the Class C Forum you will hear more good about C's, on the Class A Forum most will prefer A's. :B
We sold our 22' TT 18 months ago going to a nice 24' Class C and after 21,000+ miles haven't looked back. For us the ability to take much longer trips with all of the same, if not more amenities and none of the hassles of dragging a trailer has been priceless. I have no problem with Class A's but for our use the C is a much better fit in so many ways.
As always.... Opinions and YMMV
