We love our new 300C. Unfortunately, we haven't had any time to camp much in it. I camped two nights near the dealer to be sure everything was ok, and was very pleased to find only one minor thing to fix. I hope to stay in it 3 or 4 nights coming up in a couple of weeks.
I am currently pulling it with a 2006 Dodge 2500 long bed diesel with airbags. I have been pleasantly surprised how well it pulls. While I'm sure I am technically overloaded, it feels very similar to my lighter Sundance I used to have, except when accelerating! I do have 3750lb Nitto tires on the truck to carry the pin weight.
