I just picked up a 03 3/4 ton 4x4 6.0 Suburban with a CNG kit on it last night! It cost me 26.00 dollars to drive it home 320 miles! It is a pig for sure the dang thing won't hold 85 up some of the passes without a trailer. I was planning on using it to haul the fam around in comfort on some dune trips with the quads. I guess its time for some mods.
