- 6.7 CUMMINS
I average 10-11 mpg with my Dually Cummins 6.7 3500 with a 5th Wheel camper larger than 35 ft. The high wind resistance kills MPGs and makes it go through DEF like water. Alot of that is from the Dual rear wheels, as what it picks up in traction and stability, it loses in MPG's from 6 all-terrain tires with lots of rolling resistance.
Weight is not as big an issue as wind with a 5th wheel camper. It may be fairly light, but you will need a truck with a beefy enough rear end to handle the "wag" that crosswinds will create. A 1500 may be okay with straight line towing, but it's pushing the limits when the wind blows too strongly.
Diesel vs hemi? The choice is really yours to make. They are both capable, but it depends on how much you drive it. A diesel costs more, and unless youre going to need all the towing capacity of a diesel, and/or drive ALOT of miles before you sell it, you may just want to go with the gasser.
