I have owned a 1997,1999,2001,and 2005 chevy Z71, no issues with these, was in the truck market last summer,and glad I decided on the Tundra!! Found a 2016 model TRD Limited Crewmax 4WD, only had 21,000 miles on it, got it for $36k Love the truck!! And don't mind the 13-14mpg RIGHT NOW, pulling a load, when you turn on the Tow Haul,that thing comes alive
