Where can I get one of these cheap?? Need to turn my trailer into a "tri-trailer", as some launching areas will require unhooking the trailer. A "beach dolly" wont cut it, because of too steep an incline to the water. I'm talking about 25 ft max...say from a parking lot edge to the water's edge...which is either VERY loose gravel (my tow vehicle would get stuck for sure)...or just plain mud. When I unhook the trailer, should be easy to roll down hill. Then a sturdy tow strap or rope attached to the trailer to pull it up hill about 25 ft would be all I need. This item is $120 plus shipping. Too much. I'm also thinking about replacing my tongue jack with a larger wheel off to the side, but fear bending the tongue jack when towing up hill, should I hit a snag. Open to any other solutions. Remember a beach dolly will be too difficult to pull out of the water and up the slopes in areas I'd like to launch.
