IMO whatever you buy is a compromise. I agree GM sold out to the magic knee grow. I have never been a fan of Ford engineers but their bodies hold up well with lots of creature comfort features. I like the HO Cummins with a six speed in the Dodge but other things don't hold up and need constant maintenance. For your application the Tundra might be the best compromise.
I frequently pull a 20' stock trailer with as many 1200 to 1500 pound cows as I can get in it, or a flatbed trailer with a 16,000 pound backhoe or 16 bales of hay that weigh about 1200 pounds each. I am always overloaded. Just a matter of time until I get pulled over by the Arizona traffic control people. Watch ol' bandit run!
