Now I am curious as to the actual size differences between the two model Tundras. I was talking to a friend of mine who started using his crewcab (old body) for work towing his tractor almost daily. He toasted the trans and decided to go with a newer GMC 2500hd. Says he doesn't worry as much about it now.
Of course there is a huge difference between the '90 crewcab with a big block and a newer GM with a 6.0. All the comforts, better mileage, better acceleration, aerodynamics of something other than a brick. It just doesn't look as good.

Maybe it's the whole retro thing.
