Just a few add on comments about the Tundra, I have an 05, V-8 2wd, which replaced an '03 same vehicle.....
Both my Tundra's had the factory hitch and towing package, which includes bigger radiator and trans cooler - which I think is a must if you're going to tow for a long distance or in really hot weather.
Previously I had a 99 Frod F150. I towed a 6k lb Vermeer
chipper with both the ford and the 03 Tundra and found a couple of interesting comparisons. The Tundra's engine/trans/gearing hauled the load much easier than the Ford - MUCH easier! But, the Ford felt better, like it was more solid under the load. The Ford had 4wheel discs, the Tundra's have disc/drums, even with the uprated TRD suspension, so the Ford braked the load better.........
The Tundra back end does get a little loosy-goosy when you get close to a 1,000 lbs in the back, the Ford didn't. That said, the Tundra is so much more liveable in everyday driving than the Ford - quieter, smoother, more power, better ride etc. Reliability was not a factor on either brand - I've had no problems with any of them, although the 05 only has 3k miles so far.
Toyota is building a new truck assembly plant in San Antonio, due to open later this year, and at some point they will be building 3/4 and 1 ton trucks there.
I also have a few war stories regarding towing with what may be termed inappropriate vehicles......I towed one of those enclosed U-haul trailers (they look like a mini horse trailer) from Denver to California with a Porsche 914, I remember having to stop at the top of a couple of mtn passes to let it cool down a bit, but it hauled the weight really well.
I also hauled my boat, a 21ft Bayliner cuddy with a 145hp Chrysler outboard with my VW pickup (based on the Rabbit), however, even though it pulled the load just fine, in corners or under braking the boat was driving the truck, not the other way around! I only did this once!
What the heck, if you survive, you learn, you grow!
