Glad we aren't the only ones with this dilemma
we have driven both types. Leaning toward another Class A. I loved the drivability of the C, but was not as fond of the storage limits both in terms of the tanks and cargo. Feel the A is better for a growing family. In my search on various threads I have seen a lot of class C owners post their satisfaction with power, even when towing in the mountains- although some have done tunes or mods to get improvement over stock. Good luck to you.
