2008 Toyota Tundra Double Cab SR5 4dr Double Cab 4WD LB (5.7L 8cyl 6A)
Fragile, very fragile. 
 First the good news, this truck with the 5.7L engine gets very good MPG, hwy 21, city 15 unloaded.  Unfortunately, thats where the good news ends, I purchased this truck to tow my 5800 lbs travel trailer to and from the NC Mountains during the spring, summer and falls months, I got the 5.7L, SR5, extended cab with the tow package. On our first trip to Boon, NC we experienced the well documented reverberation and bouncing that comes with just the slightest change in road conditions..and we only traveled the interstates and four lane highways. The second thing we noticed and it also is well documented in this forum, it the shifting between 5th and 6th gear on straight road. It dents easily.
