I just bought my first dodge. Its a 2012 3500 maga cab 6.7 cummins diesel turbo. I LOVE IT!!!! But i have a question, I bought the truck so I could haul travel trailers. My question is should i chip it, tune it so I can get better fuel mileage while towing? Or is there something better I can do.?

 

What do you mean by "chip" it? (link to device please)

Tuner sure wouldn't hurt you. Don't expect it to improve fuel mileage while towing though.
