having owned a 07 tundra i agree with others here, you wont regret the move and i really doubt your mileage will be that much less than what you have now when towing.
I would make certain to get the factory tow mirror, sorry they arent as good as my super duties, but a very close second.
If you can get a good deal you'll be happy with then do it and dont look back.

I cant decide if I want the new 4.6 engine @ 310 hp or the monster 381 hp 5.7. The 5.7 is nice, but im not much of a piston head. Saving the cost upfront would be nice. I cant see us ever upgrading to a huge trailer(we only tow a 19 footer now..we picked our next one its a 23) that would benefit from the 5.7.
Also, Cant decide on Radiant Red or Black. Black looks pretty sharp too, but im worried about seing the stone chips....
I can't remember ever hearing someone complain about too much horse power, torque, payload, interior room, storage. However you will routinely hear of people complaining about not enough of one or more of them.
When we had our 19' Antigua HTT, we moved from a Trailblazer to an Expedition. I thought the V8 would kill me in MPG. But when not towing milage was only a bit worse and when towing the mileage was actually better in the Expy. Why??? Because the 5.4 barely broke a sweat with 5000 lbs. of hybrid whereas the 4.2 L I6 in the TB worked its tail off at the same weight.
I love spending other people's money, I say go for it. I doubt you'll regret it one bit.

The Tundra will get slightly less mpg when being used as a car, but the towing mpg will be the same or better than the Taco (assuming you're looking at a 5.7L V8 Tundra). The 4.6L wouldn't be enough of an improvement IMO to make it worthwhile.
The towing experience will be much better. That 5.7L is pretty stout.

Get the 5.7, most people with the 4.6 rarely get much better mileage than the 5.7.
The 5.7 will do a lot better when towing and the cost is not that much more.
Trust me, DON'T GET THE 4.6, it's a very nice engine but not much difference in mpg, especially towing. Get the 5.7 and you won't regret it. As noted, make sure you get the large extendable towing mirrors.
