Not that you need my opinion but Im going to be honest I normally do not like the flares and the roof lights. But I got to say your truck really pulls it off. I like it. Good job.

Glad to see an Sierra AT4 dedicated forum!
I’ve had my 2020 AT4 5.3L V8 10sp for a short time, but have been able to suit it up quite a bit in that time.

Nice truck. Man, you've got a whole bunch of mods on that truck. Tell me about this Black Horse Off Road Armour Bull Bar (custom fit / park sensor rewire). I always thought that the bull bar would interfere with the sensors, and I didn't know one could rewire them. What was the custom fit all about and the Trimmed / heated fender liners? I'm awaiting delivery of the same fender flares. It's nice to know what they'll look on my truck. Sorry for all the questions but I really like the look of your truck. Did you take a hit on your fuel milage with the pedal commander? I know I wouldn't be able to keep my foot out of it.

Does that bull bar interfere with the front sensors? Man, you really got that truck looking sweet.

I'm curious of the custom fit as well... Not concerned with sensor rewiring but more concerned with fitment. I ordered and sent back a similar bull bar it came in damaged. But before I sent back I test fitted the brackets and seen there would be modifications needed to brackets or bumper for them to fit through the holes for tow hooks.
