Lovin it! 
2006 Toyota Tundra Double Cab SR5 4dr Double Cab SB (4.7L 8cyl 5A)
Highly Recommend
 I had been looking at all the big diesel trucks (Dodge, Ford, Chevy) but I found for 99.9% of what I needed to do this truck would be more than enough.  The Toyota reputation really drew me to this truck and hasn't let me down.  The only bummer is the mileage (I am getting 15 in mixed driving) but everything else is great.
