Do panamericas have reenforced frames in the back
Loading up trailer with bikes for first long trip and wondering if the Panamerica was built with reinforced frame in back to support extra weight. I am planning in putting 3 dirtbikes and riding gear plus light plant and back garage. Should add up to 1200-1500 pounds. The manual say something like 4000 pounds is ok but with all the talk of airstreams having light frames I did not want to get frame seperation or other problems. I could put one bike and light plant in even in back off truck but hitch weight is already high with all tanks full. Thanks for any help.
