A thumbs up for Chevy Duty and Angie from me as well. I've also spent thousands there with no real problems. The techs at times do seem a little at a loss but in their defense most of them seem pretty young and there is no way they can answer every question. They do need to be polite and courteous though. I had a problem with wiring on a set of their gauges and by the time I finished stiring it up, the owner got involved to get me satisfied.
