Finally decided to just ditch my LLY. I'm just not a fan of it anymore. Have always liked the LMMs more. New body style, 6 speed, more power stock, quieter, less flaws.

I just want to know what the problems with these trucks are, not only the engines, but everything. I am looking at a few 08s-09s with about 70k-120k miles on them.
I planned on an Airdog-4G, full delete, down pipe, exhaust, and tuning. Apart from that, I'm not looking to make any power right now. I want to be in an extremely reliable truck. Any help or opinions would be greatly appreciated.

Motors are great. Injectors aren't prone to failure, but keep and eye on it. The dashes are horse shit if you ask me. They rattle and pop at random times. Its a NNBS thing because my buddies half ton does the same thing. My dash is cracked in 2 spots with 52k on it. One day I'll get around to fixing that. Other than that, great pickups. Plan on keeping mine for next few years less the right deal comes up. Right now I'm rolling with about every supporting mod aside a built trans and very reliable. Good luck!

How do you like it compared to your old truck?

That surprises me about the dash. Is the LT and LTZ both like that or what? I'm looking at a CCSB LTZ.

Well I came from a 2004 reg cab 6.0 so it was definitely an improvement. Not sure, there both SLE. Guess I've never known it to pop in dads SLT, but have seen the SLT dashes that have cracked.

I previously had an 04 lb7 and although that was a great truck my current lmm is way nicer. The only issue I ever had with it was a regen problem so I deleted it and never looked back. My ltz dash doesn't make any noise and there is no cracking may be a gmc thing. Definitely do a delete as soon as you can makes it a whole different truck.
