The first things I'll want to do are a leveling kit, tint front windows to match rear, and possibly a roll n lock tonneau. I might want to do something with the grill at some point.
I've been out of the truck game for 15 years or so. Just picked up a 2021 Silverado. I know at some point I'm going to modify it in one way or another, it's just what I tend to do. I'd like to avoid the crappy retailers instead of clicking them when google shows them, lol.
