Well First Off I live in the stiks, Either you have a F-350 or 1500 z71.
The only aftermarket rides are the few rice rockets that pop up, painted kawi green or orange. No F-bodys and the occasional midlife crisis vette. Certainely no Sport Trucks.
I was driving around and saw a Blck reg cab with Joe gibbs rims on it. I was like WTF.. I circled back and sure enough it was a JB edition 4.8 Magna Charged. He ordered it and picked it up in PA.

I liked finally being able to see it in person. Loved the seats, and the rest of the interior. Its amazing how neat the Radix neatens up the engine compartment.

Anyways if you can get the 55 series 20's to hook what are the 4.8 running?
It had 3.73?

 

I guess we are lucky down here in Houston. I've seen about 10 different Gibbs trucks at the various dealerships here, and two driving around. On tuesday I finally saw a Gibbs tahoe, that thing looked kick ***! Those trucks look nicer than the SS in my opinion, the wheels really set them off. Love the two tone leather/suede seats too.

 

i have heard of the 5.3's running 13.7. dont know about the 4.8's though
