I have a 01 D/A 2500 EC LB. Also have a 18 ft. Exiss 3 horse trailer. All hooked up with a BW turnover hitch (mounted 5.5" ahead of the rear axel)problem is when I haul and hit bumps or dips I nearly hit the bed rails on the goose neck. If I crank up the stinger then the rear of the trailer drags. Am considering removing the bed and instaling a flat bed. Any suggestions or advice will be welcome.
