Just under 4000 miles. This narrative is also in another thread, but thought a few more might see it here. Hopefully I will be able to figure out how to add pics, so if you are looking at this and don't find the pics, try again a little while later.
Fuel Gauge: about 3 gallons left on empty. This is pretty typical for a vehicle with a 26 gallon tank. If you are so inclined, you can put an extra 3+ gallons in after auto-shut-off, though many say this risks damaging some of your emissions (no problems yet from doing this on any of my Hondas or Nissans).
Fuel Economy: great around town, 16-17. Sucks on the highway above 70, about 13-15. Fuel economy gauge is very accurate, so you are getting what you are seeing. Mine is DC 5.7 4x4 TRD with mild RevTek lift (#437 = 2.5" front and 1.25" rear) and 305/65-18 BFG A/T's on the stock TRD wheels (= 33.6"). I tend to be light-footed, and yes I have converted fuel economy figures for oversized tires.
Tires: 325/65-18 (= 34.6") on the stock wheels rubbed the front suspension, so this size would need offset wheels. This would mean the tires would stick out beyond the fenders, which I personally don't care for. Thus I ended up with 305/65-18 (33.6"), which only rubbed the front center air dam at full lock. Bent the front air dam about 1/4" to eliminate the rubbing; no other problems. BTW, I got the lift before the tires, so I don't know what rubbing there may have been with the larger tires and stock suspension. OEM 275/65-18 = 32.1" in case you are wondering. Thus I gained 0.75" from the tires and 2.5" from the lift in height, and just over an inch in tire width. If you look closely in the right side photo, you can see the RevTek spacer in the wheel well.
Power: Yes, enuf said. Okay, it's a lot of power.
Ride: recent trip to LA confirmed what others who live there have already reported: TRD ride on certain areas of CA concrete freeways is the worst of any truck I have experienced. 60-80 seemed worst; below 60 or above 80 it would smooth out a bit. Other than CA's freeways, ride is fine for a truck, perhaps a bit on the rough side. If you live in an area like So Cal with ripples in the concrete freeways, you probably will not enjoy the TRD suspension.
Looks: this truck gets attention everywhere. Went to the Moab meet the week before Easter. A lot of impressive 4x4's in town, yet people still flocked to look at the Tundra. Definitely better looking than older model imho.
Biggest surprises: bluetooth works great, center console is huge, bed and tailgate are perfectly aligned for sliding cargo in and out.
Biggest disappointments: gauges are too dark in the day, like looking in a black hole; towing mirrors vibrate too much, especially on the freeway.
Bottom line: buy the truck. Assuming it holds up and is reliable, this will probably go down as one of the best trucks ever made.
As an aside, Toyota recently passed GM in sales, and buyers like me are part of the reason why. I had it narrowed down to either 07 Chevy or Tundra. Tundra DC has way more rear seat room than Chevy. If I chose the Chevy, I would have had to do their CC, but then the box would be too short. Tundra DC with bigger box was the logical choice. Sure Chevy had some features Tundra lacks, like digital readout of actual tire pressure, but overall Tundra is clearly superior. Thus my purchase was -1 for GM and +1 for Toyota.
Did I mention the power?
