did you look at the driver's side door pillar for a VIN plate? also check for GVW plate there too.
also, how long is the bed. is there a truck bed or a flatbed? how about tires, are they 7.00x20 or smaller? bigger? just some things for you to check, usually if you have most of these traits, it's more than likely a 1.5 ton or larger.
