I was one of the first to buy my gray double cab tundra with the supposed 381 hp engine. I bought it Feburary 1st and took it on my first test of towing. My 5500 toy hauler loaded with water, fuel, and 4 quads maybe 8700ib. My brother has a 2005 ford with the 5.4 triton and he has a larger trailer and outran me up questa grade. Doesn't tow as well as the ford or dodge. Seats feel very stiff, but overall I feel I made a good decision. Averaged 6 mpg towing and in town 11.8mpg.
Power when not towing, looks, hopeful reliability.
Seats, they are uncomfortable, needs better gearing, doesn't tow as well as 5.7L dodge ram or 5.7L chevy I had. Optional locker, I got stuck 4 times in pismo. Aired down to 15 psi and couldn't pull my trailer anywhere. Had to be pulled out.. embarassing when you pay 37k for a truck :(
