I would strongly advise against extending the ball that far from the hitch. That 5ft of leverage with only a few hundred pounds of the trailer tongue is plenty enough to bend the hitch and/or shear the mounting bolts from the frame rails of your truck.Just copying an old idea but I thought I would post it to help somebody. I made a 5 ft long bar and ball because I was having to get to deep in the water to launch my oday 25.
Man thats great. Took the original and made it betteeMy hitch extension is a 20 foot section of 2" square steel tubing, i have 5/8" holes drilled every two feet for adjustment and use two tractor hitchpins to lock it in place. I have a full deep keel and really have to sink my trailer quite a ways since the local ramp is not that steep. i have the tongue weight set light and have no issues when i have 16 feet of extension out there. Trailer pulls perfect with no issues at speeds up to 60 mph. Easy to remove and store too. Truck tires are dry during the entire launch process.
Why are so many of you going with such heavy tounge weights?
