I think traveling in a C will be much more comfortable, but when it comes to camping, the trailer will probably be more comfortable. In a class C, you either need a bunkhouse or you'll be converting the couch and/or dinette so everyone can comfortably sleep.
We had a bunkhouse C and it was great when the kids were young, but once they hit their teen years and started growing, they out grew the narrow bunks. They complained that if they moved around, they'd usually hit the wall or the blinds on the window.
Something like
Jayco's 28BHBE,
26BH or the
26BHS with its Double Bed bunks would probably be a lot more comfortable. Other manufacturers also make models with double bed bunks, so you aren't limited to just Jayco.
