I just picked up my 2010 Tundra, reg cab, 4x4, LB, SR5, 5.7 truck. After only one small road trip, I am impressed at the Toyota quality. Coming from a Silverado the past 2 trucks (11 years), I can say I am glad I made the switch. The 5.7 seems to have awesome power (yet to tow anything). The space behind the the seats is massive and will fit most anything I could want back there except a person (comfortably). The ride is acceptable for a truck. My only concerns/complaints so far is the storage. There is no map pocket in the back of the seat. The center storage is also a little slim. With that said, I didn't buy the truck for storage...I bought a truck to use it as a truck.
Power, comfortable seats, good ride and hopefully Toyota reliability (time will tell).
More storage in center "flop down" and a map pocket in behind the seat.
