Decisions....Gas or Diesel

I own a few of each- pull trailer loaded with all sorts of stuff to make money with heading to jobs for my company.
Diesel is my favorite.
My gas 4x4’s burn typically 9-10mph pulling 20,000lbs. New trailers with dual axles-
Typically 14,000gvw tilt decks.
My diesels pulling same loads is 12-14mpg.
Those are honest figures- the dash computers are good but math says otherwise. I also drive heavy footed. So take that information as well.

I also appreciate diesel exhaust brakes. Saves on brake pads - a lot. Gas trucks use 1.5 more brakes than diesels per life time of same mileage. Other thing to consider is trim levels.
If you are driving empty all the time but a few trips then diesels are not for you. You cannot recoup the extra $7k for a diesel with gas savings.
Also, real trucks don’t blow black smoke- that is unburnt fuel. Looks like crap and makes a mess of the truck. Yes it is a sign of a “turned up truck.” Remember these trucks were designed for approx 400,000 miles per engine (diesels) when you turn them up you remove from the big end mileage. Wear and tear. Sadly you need to modify a new Ram diesel some because the emissions on the 6.7 chokes them off, regen sucks. Leaves you dragging butt every time. Off soap box. Hope I helped.
