I have a 6 footbed and haul a 12 foot jonboat around..WITH the aid of a product called " Extend -A- Bed" ...It is a steel arm that slides into a stanard receiver hitch. The end comes up with a horizontail bar and two side arms too hold the rear of the boat,,,ladders...lumber...etc....you could add triller lights for added safty if your handy...look for it on the web. or truck /Auto supply... There are two brands out that I know of...surf /search and you will find them..I love mine!
