Typically, I can 'get by', but I do have occasion to do more than what's best for any half ton truck. I'm more concerned with durability/longevity. My towing and hauling and off-road is generally a weekend affair, revolving around hunting, boats, tractors, ATV s, and mild off road stuff. Long road trips, often. A heavier built truck probably lasts longer when used as a truck. I could also maybe grab another car for commute stuff to save wear on any truck, if I had to. Do I really need a 3/4-1 ton diesel? You're prolly right... but I could use one over a half ton, on occasion, and it might live longer....not sure.
