If you're not pulling a trailer there's no need for the diesel. My F250 is over 9,700lbs fully loaded and the gas motor does fine in Colorado. The trucks you're looking at have even more gears in the transmission so they'll do even better.This might be the toughest decision of all of them, So far I can establish two facts:
1. Diesel Engine is $12+K more expensive and heavier.
2. Diesel Engine has way more torque at low RPM which comes in handy where I live. But even this needs to be tested, hopefully dealers let me take it to a very steep and rocky climb and "feel" the damn thing.
All the other claims about fuel efficiency/cost, reliability, maintenance, availability are subjective depending on ones particular needs. I'm biased to like diesel, but my wife has me in check, asking me for real reasons and solid evidence, so we have that going for us.
2 other considerations. Diesels don't like short drives. Is your day-to-day use going to be hard on the emission system? Are you keeping it in the garage? If not you may want to consider plugging it in during the colder part of the winter.
