I'm approaching 190k miles on my '06 Tundra. I drove it off of the lot with 9 miles on the odometer. The truck is great and have had no major issues with this truck. I have replaced the front brakes twice, the rear once. I have replaced the serpentine belt and spark plugs only one time. It seems the older the truck gets, the better the mileage is. Currently, I'm getting 17 mpg running regular unleaded fuel. I've had no leaks on any of the seals on the engine, transfer case, or differential. The truck rides as if it was new, with little road noise, vibration, or any unusual sounds that would raise concerns. If you are in the market and can find this truck with low mileage, I highly recommend this truck. My only complaint is that it only has the 4.7L 271hp engine, which is weak, but it will pull your trailer if you find the right gear.
Owned a T-100 SR5 as a dealer offer for a problematic 98 Tacoma lemon. Great truck but the later TUNDRA was THE answer. Now on my 5th Tundra(all have been used buys). 2 Access Cabs(the rear door opening was a pain) and 3 Double Cabs(1 SR5 and 2 LTDs)-always a superb performing tool and toy for fun. Just found the latest Limited with all the options in NYC - 14,000 miles and drives as new as it was only used to drive to church on Sundays. For those hauling/towing a load-yes-the 07 and newer do the job better but for a roomy truck(no towing) that rides/drives like a luxury vehicle on the highway/none better. The rule is how much FUN do you want to have and HOW MUCH are you willing to pay for that FUN! Some want a Porshe-some a RAM/F150/SILVERADO. The 06 TUNDRA DOUBLE CAB 4WD LIMITED is my FUN and does it extremely well as it was the last year of that body style. Air bag recall a noted problem but not TOYOTA's fault-Takata's fault! Just wished I would have bought one new in 06! So choose wisely on YOUR version of FUN! And enjoy the RIDE!!!
Got as my first truck and have since put over 20k miles on it, and even though im just turning the corner too 200k, still runs flawless. enough room in the back for a dog, guns, and waders. big thing for me was the bigger bed, buddys got a tacoma and cant put anything in it. i can fit two mowers, two edgers, two blowwers, two weedeaters, and couple bags of debris in mine. All around solid truck and the v6 is solid and pulls my 18 whaler just fine.
The double cab gives this truck a very long wheelbase which is great for ride comfort, but bad for turning radius. Also, it makes the truck heavy, so fuel economy takes a bit of a hit. Probably between 16 and 17 MPG on average. Some of the radio controls became "wonky" or uncooperative with age. If you're the "do-it-yourself" type, some standard maintenance tasks are pretty simple on this truck. I replaced the serpentine belt in about 15 minutes having never done one before, and I also replaced the front brake pads and rotors in an afternoon. (I tried to get the rotors turned, but they just needed to be replaced, so that ate up some time.) For auto-mechanic ability, I'm probably about a 5, but these jobs were easier than I expected.
This is the perfect size for a truck. I've owned three F150's and none felt as comfortable as this truck. So far I've had zero problems (other than it loves to drink gas). My mileage will actually go down and I expect to hit 100k miles around year 2025. With Toyota holding value so well I expect to get most of my money back when it comes time to sell (just before 100k miles).
