Greetings. New guy here, so please freely call me out an any forum missteps.
I started out with a base model 2018 GMC Sierra 4wd, regular cab, standard bed. It has a snow plow package and 3.42 gears. Onyx Black. No frills. I'll try and remember the order in which I did everything. All work do date has been done in my driveway, which I'm reasonably proud of because I work a job where I mostly send emails and sit in meetings.
-- Debadging happened the first day of ownership... just my thing, costs nothing.
-- Blacked out my front badge with with plasti dip
-- Removed the air dam
-- Cover King carpeted dash mat added, in the color of 'wine'.
-- Cover King saddle blanket seat covers added in wine/whiteish.... returned after about a month because they were coming apart at the seams in a quite literal sense. Back to my grey cloth seats.
-- Added a Rough Country 2 inch level (those cheap spacer things that are shaped like 'C'
-- Brow tint on the windshield and multiple layers of Collinite way done by Motoring Images in Lee NH (ok, this wasn't in my driveway)
-- Airaid modular intake and filter added. Sounds great, I'm a fan.
-- Borla ATAK cat back system with polished tips. Sounds wonderful.
-- Diablo Intune3 handheld tuner, custom (non dyno, remote) tuned further for 91+ and some extra oomph by Lew.
-- Mudflaps installed and ultimately removed because they were the no drill kind and drilling would have helped from losing one in a carwash or who knows where, so those are gone.
