Dodge - Diesel or gas?
Which would you choose and why?
Depends on the job the truck will do. If its just hauling 3k-5k TC around with a small trailer the 6.4 hemi will work great.
You pulled a 5er so you understand the benefits of the diesel pulling 14k + trailers, so the 6.7 Cummins is a better choice.
IMO its a mistake putting the gasser ahead of the diesel for best braking performance. The 6.7 turbo brake has no equal in a gassers braking ability.
But the new gen 3500 SRW Ram with the Hemi will have no problems stopping the TC load. Truck makers have vastly improved our trucks braking systems the last several years.
Tough choice but IMO in your case of moving a small load and no pulling a heavy trailer I would lean hard toward the 6.4 Hemi from a up front cost perspective.
Make cents/sense to me.
