2005 Toyota Tundra Regular Cab 2dr Regular Cab 4WD LB (4.7L 8cyl 5A)
More than I ever expected!
 I upgraded to this truck (Regular Cab
4WD V8) from my V6 Tacoma because I
needed more hauling power and more room
in the bed.  I have driven this truck
11,500 miles in 6 weeks, sometimes
hauling a double axle 16' car trailer
and loading heavy car parts in the back.
 The Tundra's fuel economy while towing
is much better than I expected,
especially with non California gas. 
Build quality is excellent, with my only
complaint being the cupping of the front
tires-the dealer found the front end
alignment to be 7 degrees off!  I bought
the strip model with real window cranks
and rubber floor mats for ease of
maintenance.  I drove them all,but one
thing was missing-the Toyota reliability!!!
