Long-wheelbase family haulers; ¾-ton 8-lug versions rare.
The Suburban and Yukon XL are the same bones on GMT800; your choice comes down to trim packaging, branding, and the Denali variant.

The first-generation GMT800 platform family (1999–2006 for pickups; 2000–2006 for most full-size SUVs) is the era that brought GM’s full-size trucks into the hydroformed-frame, LS-based Vortec world. “GMT800” is enthusiast shorthand for the shared chassis and drivetrain DNA across Chevrolet, GMC, and Cadillac — and it’s the reason a lot of parts, service logic, and […]
