Just got rid of a Ford 350 diesel, 2014. Right off the showroom floor, it wasn't as tight as our Tundra that had towed the trailer from here to Dawson City, down through Oregon, to Nevada, to Bella Colla and all over Montana and Alberta. every so often, the directional signal module would detach and hang loose, but the dealer had to se it happen before looking at it. It got about 11 towing, just a mite better than the Tundra, and when a bearing wrapped around the crank and we had to sit beside the road in the freezing rain out of Pincher Creek waiting for a tow, then rent a car and drive back to Montana to get the Tundra to retrieve the trailer, and then wait almost three months while they replaced the engine, my love affair with diesels had waned.
The Tundra has power enough but has over 120,000 miles on it and am thinking a real 3/4 ton truck might make a better compromise every day truck/tow rig than another Tundra.
