I love the truck it is very comfortable, and has been trouble free for 5 years, till I noticed the coolant level dropping, I figured out it had cracked cylinder heads. Took it to Boulevard GMC in Signal Hill and they charged me $170.00 for something I already knew and lied and said they took the valve covers off to inspect, when it shows no one has taken the valve cover off, (BEWARE OF THIS DEALERSHIP) GM wont help pretty much had to fix my self. I put in Bars head gasket fix and the leak in the heads went away, been 3,000 miles all I have to do is change my lifters and push-rods and should be good to go. Don't think I am going to be buying GM anymore.
