Thanks for all the replies. It's been really fun. I'm so glad we got this size and floor plan. It's just the two of us, but our dogs do require a bit of room. Especially the 94 lb Lab.
I did make huge mistake the first day we bought it though. Since I figured I'd be towing it home with the Titan I decided to empty the Fresh water tank that the dealer had filled. The system was on the water pump, and the electric side of the water heater was on.
I was letting the water out of the faucets and noticed it start to sputter, and then I realized the water heater was still on. Guess the element blew out, but I didn't realize it until I noticed a breaker tripped. Yep blew the element. Glad the gas side works. I can't believe I did that. I'm usually much more aware of what I'm doing.
The Dodge 6.7 manual says no break in required. In fact it says towing a lighter trailer will only extend the time it takes for the truck to break in and start getting better fuel milage. I'm living it all.
