I built the rack.
I am most likely over GVW (10,100) with everything loaded, but front axle rating from Chrysler is 5200 and rear is 6200. Empty truck was 7950 lbs, truck is naturally nose heavy but assuming it is balanced that leaves 2,225lbs capacity over the rear and 1,125 over the front axle, total. We pack fairly light, with most of our other crap in the trailer. Trailer has pair of 3500 lb axles and dry weight of 4200 lbs, btw.
I will have to get a scale ticket so everybody can get some rest next trip, or I can find a savvy lawyer to land my load onto.
