6500 would denote a 2-ton. It also looks like the dust cover for the front wheel bearings bolts onto the hub. 1 1/2 ton did not bolt on, those are t-ton. Looking at the front wheel, ot looks like you have 10 holes but only 5 are used (all 10 used on the rear though). 1 1/2 and 2 ton are like that, so, it looks like you have a 2 ton truck!
