Hello all. I am a new member. I am picking up my new 4x4 3500 dually mega cab Laramie 160.5" this Saturday. This will be my 3rd cummings. Previous diesels: 1999 dually 3500 QC 2wd 160.5", 2003 Chevy 2500 crew cab 4x4 Duramax/Allison, 2007 Dodge 3500 dually 4x4 crew cab 160.5". I have read several topics and threads and have already learned new stuff. Thanks for all the info and if I can help anyone out I'll do my best! Thanks for the opportunities!
