All I can say is don't buy this truck. Its the biggest piece of $#!^. Its no wonder GM has to shut down half of their factories. Used to be die hard chevy man but the past two that I bought cost me more in money, time, and soul than any other car manfacture. This 5500 has only 47000 miles on it and its broke down 5 times. The gauges quit working and now its on the side of the road waiting on a tow. Duramax??? Dura what?? Made by IUZ_U!! I've had three Fords. One I sold with 220,000 miles on the original 460 running strong and another a powerstroke with 147000 miles still on the driveway laughing at the gm in the shop. I'm done complaining. FORD ALL THE WAY!!!!
