We made the switch from our 22' TT to the 24' C last summer and have not looked back. In a word, it is EASIER! After 7 months and 10,000 miles we love the simplicity that the C brings to the RV/Cruising/camping equation. I do miss the voluminous storage I had in the back of my SCab F-150 with the Leer Shell but that is about it. I used to get 11/12 mpg with the truck and trailer and now get 10 with the C but with a 55 gallon fuel tank it has more than twice the range.
The interior storage is far better in the C, we currently use about 60% of the available space, and having gone from a middle of the road trailer to a high end C the amenities are amazing (upgraded appliances, electric awning, heated tanks, bigger and better beds). We were 46' long nose to tail with the TT and now it is 24' . Do we miss having the truck to drive around? Sure, but not that much as the C will go just about anyplace the truck would.

Part of the reason we are so happy with the switch is that our trips have changed from mostly camping to longer, extended road trips. We still camp almost every night, we just do it a lot farther from home. There are so many wonderful places to see in this great country and the C makes getting there so much easier. For us the journey is now at least half of the fun.
As Always.... Opinions and YMMV.
