2009 Toyota Tundra Double Cab Tundra Grade 4dr Double Cab 4WD SB (5.7L 8cyl 6A)
After First Month
 Great Engine and Transmission. Feels Solid and drives great on most roads. Toyota has a real issue with the bed hop problem on concrete roads. Been to dealer twice for this issue. No help from dealer or escalation to Toyota district rep. Seems to be a design problem and Toyota trying to say it is suppose to be that way. No way. I am changing shocks this week, at my expense, to try and address this issue. Hope it helps..
