ABSTRACT:
A kit is provided for attaching to a road travelling mobile platform (e.g. a wheeled trailer or a self-propelled vehicle such as a pickup truck or a flatbed truck) suitable for transporting a first vehicle. The kit enables the mobile platform to transport a second vehicle, such as a boat trailer carrying a boat, thereon. The kit includes: a tiltable ramp suitable for supporting a boat and boat trailer thereon. a first support for supporting one portion of the tiltable ramp in an elevated position with respect to the mobile platform; a chain and drum located on the first support for securing the boat and boat trailer to the tiltable ramp; and a second support capable of supporting a long lever arm portion of the tiltable ramp in an elevated position or capable of retaining the long lever arm portion in a lowered position. The first and second supports include connectors for connecting the mobile platform to the respective supports. The first support also includes a fulcrum serving to divide the tiltable ramp into a short lever arm portion and a long lever arm portion. The chain and drum and also adjustable wheel stops enable selective movement of the boat and boat trailer towards or away from the fulcrum to locate the center of gravity of the tiltable ramp and boat and boat trailer over the fulcrum. The second support for the tiltable ramp includes a lock for locking the ramp either in an elevated or lowered position with respect to the second tiltable ramp support.
