Hey all! Just purchased my new '13 LML ECSB LTZ Z71 black beauty a week ago. This is my 9th new Chevy truck purchased over my 39 years on this earth, first diesel! Came from a '10 1500 with the 6.2 and the fuel mileage when towing just wasn't cutting it anymore. Tow snowmobiles and atv's frequently with a 23' enclosed trailer. Right now as far as mods, looking at leveling it and maybe exhaust in the future. But that will be about it. One question I do have is if I level it, how will it ride? Right now I think the ride is great and I do not want it to get any more harsh at all. Thanks all and look forward to great information and talking to great people!
