So what are the must-do mods for this truck?
 

Just picked up the 2016 Z71 crew cab, 3.6L, loaded. Already removed that stupid air dam and had the dealer install a spray in liner and leveling kit...

What's next? I see mixed reviews in the K&N air filter in other forums...

The stock tires are ok, but I wouldn't mind a step up in size... what do the stock wheels and wheel wells accommodate?

Any other tips and tricks, or just drive the s*&t out of it?
