OP says 9500 and 2922 so truck weighs 6578 with full tank without any passengers or cargo. My 6000 plus cc vs ext cab and the 4 x4, plus his heavier frame to get that 9500 vs 9200, would be about 6578, so that works.
Scale is 7826 so minus 6578 = 1248 being carried. OP says just him and the canopy. Don't know about 2012s but my 2003, you can go with wider (heavier) tires but need wider (and so heavier) wheels. Perhaps OP has that done. Belly bars? Running board bars? The canopy probably weighs more than the OP thinks too. Hitch in the receiver?
