Yes, your current 20 inch tires are 1 inch taller than the 18`s

Looks good!! maybe get the front windows tinted and add a stubby antenna

Well I dont know about the GMC but that is only 32.58 tall tire , I have a Silverado RST and I put on TB lift and I put on 285/50/22 Nitto Ridge Grapplers which are 33.22 tall have have no rub at all.

What lift did you go with? and tire size? I have the basically the same truck only the RST Rally with the 6.2 and I put the TB lift and went with 285/50/22 Nitto ridge Grapplers

I went with the Nitto Ridge Grapplers , aggressive side wall and nice and quiet.

I do believe it does void the warranty if not done by GM service , but how does it sound ??

I was also looking at both, going back and forth and ended up getting a Black RST with the 6.2 and 10 speed transmission, I just didnt like the huge front end of the GMC but the 10 speed is awesome.

Nice thank you!!

what kind of bike rack is that ?

I swapped out my Bridgestone Aleza`s for some 285/50/22 Nitto Ridge Grapplers much better tire.

The tire size is one inch larger on the 21
