[mrbuck123456]

Looking for the specifications on the 830 & 880 platform or does anybody know what the differences is. Will a body off the 830 sit on 880 platform? Are the electrical systems the same in the 2003 and up?

The 830 being the fullsize SUV and the 880 being the fullsize truck

 

The GMT 800 and similar GMT 880 was the basis for the 1999-2006 Chevrolet Silverado full-size pickup truck. The derived GMT 820 and GMT 830 was used in the Suburban, among other full-size SUVs. This is the successor to the GMT 400 series of C/K pickups and SUV's.
