Is the GMC Sierra 1500 AT4 worth it for El Paso drivers?
Yes, the GMC Sierra 1500 AT4 is worth it for El Paso drivers who leave the pavement or tow, because the maker builds it with off-road hardware the lower Sierra 1500 trims do not carry. Group 1 GMC Westside sells it new at 955 Crockett St, with used and certified pre-owned GMC trucks alongside.
Off the pavement and behind a trailer, that hardware is what the premium buys. The price, engine and tow figures show what it costs.
Keep reading below, then schedule a test drive in El Paso. Bringing your own numbers to the lot settles this faster than any spec sheet.
El Paso off-roaders get the most from a GMC Sierra 1500 AT4
The AT4 suits El Paso drivers who take their trucks off the pavement because the trim carries hardware the lower Sierra 1500 trims do not. The maker lists a 2-inch factory lift with off-road suspension and Rancho monotube shocks, underbody skid plates and a two-speed Autotrac transfer case. Those parts matter on loose sand, rock and trail, and on a trip where the truck pulls a trailer to the trailhead.
A Sierra 1500 that stays on the freeway and never tows does not use that hardware. For that buyer, the lower trims cost less for the same daily work.
