One of the cool items we bought when we purchased our Ski's was a DUAL or SINGLE connectable trailer. The purpose is to allow one truck to carry TWO ski's or two trucks to carry ONE ski each. This way If I want to take MY BOAT I can hook the two trailers together and then use one truck to pull the ski's and another to pull the boat. It works great, is very stable and gives us great flexibility when heading to the water. Made by Karavan you should ask your local dealer if they carry them or can get one. We did and for two of them it cost a total of $2000. If you see in the picture it has an extenstion that allows the toungues to connect togther for single towing.
