was just reading through the thread.
If you like to buy gas... something like a 07 K2500 GM pickup with 6.0 gas engine is worthy ( I have the new body style).
I doubted the ability of the 6.0 engine until I bought one.... has 6 speed automatic, 4wd, 3.73 gears.
Avg mpg on hwy something like 14-15 unloaded... towing my crap... in the hills around 7mpg, on flat ground 9.
The dmax of the same year is one of the best in my view (in the gm line) ....but you'll pay 5 to 7k more for the dmax vs the gas engine in the used market from what I was seeing in the GM line.
I'm towing approx 9K in weight (trailer + FJ60)... If I were to go with much more weight I would jump over into the deisel game.
I like the 7.3 Ford, and some of the Cummins dodge trucks. But would prefer a manual trans with both.
Just throwing it out there for the gas burner if someone was not towing heavy (north of 10K). I purchased a better trailer hitch as the GM OEM version is not suitably rated for a 3/4 truck.
