i live in upper michigan and have had 8 trucks in the last 18 yrs. i love my 2008 sb 4wd reg cab 5.7 tundra. nicest and hottest truck i've had. BUT it's the worse 4 wd i've owned. won't lock and in the mud and snow in the U.P. it's been a huge disapointment. everthing else beats all comers that i'm surprised that no one has challenged them to fix this. it's never a good thing when your pulled out by a chevy that is so inferior in all other aspects. not the tires i spent 1200 bucks on off road michelins.
