I mentioned in earlier post how wonderful our truck is. Not to detract at all, we have two warranty corrections. Dealer replaced the receiver assembly when we noticed the pin hole in the receiver was wallowed out pretty badly. Dealer said he'd never seen this, but he did not hesitate to replace it No Cost.
I complained to Ressler Chevrolet in Bozeman, MT, of high oil consumption on my 8.1L Vortec. I'd heard these engines were bad for this and might have some dealer/mfr magic they could work on it. He said, No, not for the 2006 but let him look over it anyway. Bingo! They found a cracked oil cooler line, replaced it No Cost. Gave me a GM form to log oil consumption in case it still seemed excessive. Treated me great, got me in and out in under a few hours with the oil leak check, replacement of the cracked line, and an oil change. Very fine customer service, very fine service to my truck. I'll go back next time I'm in Bozeman.
Six weeks and 2,600 miles later, the dipstick oil level is unchanged. Sweet.
The only mods we've made are a tonneau cover, a transfer flow
replacement fuel tank to upgrade from a 26 to a 45 gallon capacity, and a bunch of 12v
and coax wires for amateur radios.
Gas mileage isn't much to write home about (maybe it'll improve after we get it broken in, only has 26,000 miles on it), power is what we expected from a big block V-8, exhaust sound is better than we expected (quieter than any diesel but has a very nice rumble), seats (cloth captain) are most comfortable of any we've had (vw, audi, mazda, honda, volvo, bmw). What a great truck!
Guess I'll try a Dodge next time, or a Ford, to see what I'm missing, you know? But a diesel? Not in the foreseeable.
