Seems like everyone I talk to regarding their tow vehicle, regardless of Gas or Diesel, is how good their MPG is for their vehicle.
With my truck, I average about 15-16 mpg overall when not towing, and then when I was towing a 24 ft TT, it dropped to about 8 - 9 mpg. The good news is when I went to a larger 5thwheel, it went up to about 9-10. Other than wind resistance, I can't explain the difference. This is with a 5.7 Liter Hemi Dodge.
Otherwise, my personal experience with GAS versus Diesel has been working on Ambulances and farm equipment, and how much fuel you use in those vehicles. Where I really notice the difference, is when you sit and idle in an ambulance - which is most of the time, since you have radios and computers(GPS) running all the time, the Diesel wins without a doubt. It seems like on a long standby, 4-6 hours, with the Gas engine ambulances we'd use as much gas as if we drove 300 miles ( common trip). Where the diesel ambulances would only sip a little when idling, but get about the same mpg as Gas when actually driving.
Seems like I hear when towing the diesels get the better mileage, but this doesn't seem to match my personal experience in ambulances? There are some differences based on the government requirements for engines in Ambulance, so that could be part of it, but I don't see that much difference in size/weight ( By the way, the legal requirements for ambulances are in section KKK of the DOT code - Don't ask me why KKK?)
Anyone have personal experience?
