Oh I completely agree but did it as overkill. It's also nice to be able to run veggie oil (90 gallons I put in my aux tank for distant tracks) and still get 20 mpg running around in the truck...or 15mpg while rolling with GCVW of 15,000lb at 85 mph
If you get an old 12V Cummins, 22-24 mpg while towing isn't unheard of.
but yes, a used F150 for $8k will get the job done, no sweat.
