To the OP, an update to my earlier post...
A few days ago I bought a 2014 4x4 CrewMax Tundra SR5 upgrade. I did this after looking further at Ford, Dodge, and Chevy. So far I am pleased with it's comfort and performance (381 HP 5.7 Liter). I have never owned a truck that powerful before so I have nothing else to compare it to.
Passenger space is insanely generous and is better than any vehicle I have ever experienced. You can fit four very tall adults in it very comfortably. I am 6-2 and I still have plenty of room to move the seat back from a comfortable position.
In regards to the 4wd feature, the Tundra allows you to turn on/off the limited slip differential in the rear as well as turn on/off traction control system. The tow mode will be handy if you do any towing and want to change your transmission shift scheduling. Also, if you want to tow something there is no need to add a receiver hitch and trailer hook up since its standard equipment.
Another thing I learned driving it recently is that the transmission downshifts when I coast to a stop which is kinda cool IMO, its not annoying to me in that it seems to know when I want to coast towards a stop. I am guessing it looks at pedal position and figures if you lay off the pedal for so many seconds it figures you want to decelerate towards a stop or slow down. I haven't tried it in cruise on hills, but I would imagine it downshifts while going downhill when the cruise is on to maintain set speed, however I dont know that for sure just yet.
The headlight level adjuster wheel is pretty handy. If you have a heavy load and are a tad nose high you can scroll the wheel to adjust your headlight beams.
The Entune radio deck/hands free phone is easy to operate. The voice recognition does a good job understanding me. You can change the screen layouts so that your "home" screen shows what you want.
The cloth material is way better than the other manufacturers in my opinion and the different color seat panels is kinda neat. The console storage is cavernous and proably could fit a small cooler, but I have yet to try that so I'll have to report back
. There are 4 power ports: 2 front, 1 in console storage, and 1 for rear passengers. I have no idea what kinda wattage I can draw on those yet.
Something I thought weird when I looked it over before taking delivery: it has no transmission dipstick! I have no idea why that was deleted.
Nothing in the interior seems flimsy as far as I can tell.. the only thing I think might break would be the power port cover in the passenger area. Its a spring loaded plastic door but I dont think thats a big deal if it happens. The door handle wells have a piece of felt in the bottom of them, I dont like that since my kids leave their sticky lolipop sticks and candy wrappers in there when I am not looking. However they look to be removable.
I think it will be like our family Camry... perfectly boring with no exciting breakdowns or "wtf" type of moments

There are Tundra specific forums out there that I would recommend checking out. I learned a lot about the good and bad of the Tundra. I don't think you'll be disappointed with the Tundra unless you have a specific requirement that it wont meet.
