I have a 2011 Ford F350. The box of the truck touched the front of AMPED bulkhead and damaged the truck box. Has any other Ford owner experienced this problem? I was told after I purchased unit that Ford boxes do not go under (clear) the indent of the molded front end cap of the AMPED 28 ft. The Trailer reach is to short??? If I extend the hitch from the truck it lowers the ball limit below specifications of the trailer's tongue weight, (varies 1400 to 2100 lbs.). Any solutions?
