I bought this truck to pull a 30 foot fifth wheel camper and to travel in. The first time I had a chance to pull my camper the Cummins engine had the rig going 80 MPH mergeing into a interstate highway off a ramp with lots of power to spare. This truck and engine combination cann't be beat for comfort and power. The first mpg for towing a 12 foot tall, 30 foot long fifth wheel camper was 15 mpg. No bad at all for only having 1500 miles on the truck and not being broken in.
Cummins engine has it all, power, fuel economy and quiet too. The Laramie interior with heated leather seats is soo comfortable. Let's go cruisen like kings of the road.
They need to have interior release fuel door, after all 30+ gallons of diesel is a investment a $3 a gallon. Also the Dodge rear wheel well liners will not fit 3500 trucks because of the over load spring bracket hits and would rub if liners are installed.
