We decided when we started RVing that we didn't want to have to learn to back up any sort of trailer, including a toad. We also like to keep moving and not stay in any one place for more than 3 days at a time. This left us with the option of a B or C since we felt we would need a toad if we had an A. We went with a 21ft C to start with. But with 2 big dogs, this was a bit small. We are now the happy owners of a 24ft Lazy Daze class C with twin couches in the back. It feels HUGE to us compared to the 21 footer with the queen bed but we can still take it almost anywhere. We feel this is the best RV for us and hope to have it for many years.
