So I just got done going through all 26 pages of your thread and I gotta say, nice job Smith! My 13 RCSB Sierra is almost the same model as yours, except mine has a 4.8L and no onstar. Like you, I've been wanting to do up my truck the way I want to but sadly, life happens and plans change. All I've been able to do is take the badges off, tint the windows, and install some 2" lowering shackles
and I also for a lil while was thinking of trading it in for something bigger but I decided to keep it since I'm using it to build up some credit and because it has value to me now you know? I'm starting a new, better job soon anyway so maybe now I'll have some extra cash to spend on it. Anyway, great thread and I hope everything works out for you and you get to build up your ride like you planned, I'll be following
