I drive a Nissan Frontier so I might not qualify to answer this. But in my regular day job, I haul 150 gallons of water, Polaris Ranger 6x6, pull 3000 feet elevation change in less than 20 miles on gravel/dirt roads. Done it with 2500 Chevy gas, just a little slower. But I think key to any hauling is a gear ratio of the transmission that you can actually tell the difference between 1st, 2nd, and 3rd gear. The diesel is really nice to have coming down. My favorite trucks out of all the ones I have driven are: 1999 Dodge Cummins 2500- loaded it with 2 bundles of 12 foot 6x6 and drove 300 miles. 1997 extended cab long bed Ford F250 Powerstroke Diesel-needed a 40 acre field to turn it around but I could take it anywhere. 1999 5.2 L Dodge 1500-use to have to go out in the mornings and pull the Meadow Gold Semi-Truck out of the loading dock when it was icy.
I do very much dislike the Ford V-10- I have to fill it up every day and it is screaming coming off the hill in 2nd gear.
