On my LML I use the stock rotors and pads front and rear. I am a transporter so there is always a trailer connected to the truck. I am on my 2nd set of front pads - stock GM pads. The original pads went 300k, replaced them and did not need to turn rotors. I am still on the original set of pads on the rear, as well. Just turned 466,244 miles on the truck today. My trailer brakes are a different story - leak seal has ruined some shoes. I am starting to have issues with my abs system and will be changing it soon, as the wheel sensors have all been changed and I still have problems with braking on exit ramps and when on getting onto the highway from circlular on ramps.
