Bought the truck Dec. 16 2007 assembled in Texas. So far have 12000 mi, had no mechanical problems and no strange noises.the truck does bounce some on the freeway when there is nothing in the bed. There is one thing I don't like and it is at the dealers now for, and that is to have the radio replaced. There is static, scratching noise in the AM section of the radio when I hit little bumps on the road or freeway. Otherwise the JBL 440 watt 12 speaker 4 cd radio sounds very cheap.
