With a 2016 Tiffin 32SA on the 24,000 pound chassis I tow a 2019 2WD Explorer that fully loaded weighs 4930 pounds (including the towing rigging--plate, connectors, tow bar and drop bar). I'm 70 pounds under my hitch rating and at 27,500 pounds total of loaded coach and loaded car 2500 pounds under GCWR. All works properly, the car tows fine, no sweat.
I was a field construction boilermaker out of Local 1 in Chicago and I did a lot of heavy rigging building powerhouses, refineries, blast furnaces and such; some lifts over 300 tons. I have no problem working equipment right up to it's rating but I won't go a pound over or a foot out too far. And you have to know what things weigh to do that.
