Your right since he pulls a D7 on a trailer behind him to work each day he probably should have the Cummings in it.
I thought this was about him having a little more power and getting some mileage going to and from work.
Sure, but IMO, the 318 won't get much if any better mileage than the 360 simply because of the weight and power difference. The 318 will be using a bigger percentage of its available power.
