While it looks impressive that my Tundra isn't squatting too much remember that the center of gravity loation on the trailer can be shifted by moving the Ford forward or aft changing the tongue load to an acceptable ride level all the while keeping positive download on the hitch for stability. That trailer is an H&H Speedloader with 12K weight rating and I like it mucho.
Diesel trolls don't bother me. Heck, I own more diesel pickups than gasoline types. We're flat done with buying new diesel pickups for now. Things are not as they used to be and the numbers just don't add up. The initial cost of diesel power package, the new EPA mandated fuel economy reduction and associated emission equipment up-charge, diesel fuel price $.40 more than gasoline, the inability to use all types of diesel fuel (they don't have ULS in Mexico where we travel occassionally), and overall maintenance & parts cost has effectively nixed the idea of us buying any new diesels for the foreseeable future. I hope things will change someday but right now the diesels are a mess. That's one of the reasons why I bought a Tundra. While the Tundra and diesel 3/4 tons can't be directly compared due to the proverbial "apples and oranges" argument, I theorize that most private pickup owners have more truck than they can effectively use and many times the same is true for commercial operations, albeit without the personal owner's emotional component of the pride of ownership. As an example I bought a container load of 4x4 Japanese mini trucks straight from Japan and make my employees drive those at work and park their pickups unless they have to go to town or do highway driving. We eliminated the preposterous action of cold-starting a $40,000 diesel pickup to drive 1/2 mile and get a hammer out of the shop.
I know there are many applications where a diesel 3/4 ot 1 ton truck still makes sense such as hot shotting and there will always be plenty of market for them.
