Cody, my salesman, was professional, helpful, honest, and a pleasure to work with. There was no pressure at any point during the process. JP, the sales manager, was also easygoing and pleasant to work with. They were both very accommodating in negotiating a fair price—They even allowed me to inspect the underside of the vehicle, which I really appreciated.

Had an internal leak which, as I thought, turned out to be an air conditioning issue (cracked/damaged evaporator case). Dealer did the right thing by also replacing all interior carpet, insulation, and pads due to the water damage that occurred, even though it required the complete disassembly of the interior (seats, trim, dash, steering wheel, console, etc.). All covered by warranty. Also gave me a loaner vehicle during the repairs.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.
