I read the questions and answers on 3/4 ton 6 lug bolt patterns. '95 gmc 2500 abx 4x4 6 lug. is it a 3/4 ton?

or is it one of those "heavy halfs" that i just read about? badging is 2500. i own a 2003 3/4 ton 4x4 and a 2009 3/4 ton HD. the rails are thicker on both than on the 95 i'm thinking about buying. Where rail runs over the back tires/axle on the 95 in question even gets about 3-4 inches shorter (in height). Is this a 3/4 ton truck? A real one? It only has 6 lugs.
