''when it comes to launching, closer to the water means not as much vehicle down the ramp. 10" wheels allow the trailer to hug the water a little more for launching.''
My trailer has 12'' wheels, and launching I can see being a problem so yesterday I purchased 20' by 2'' square 11 gauge steel beam. it will stow (with brackets) under the centre frame of the trailer. Then at the ramp install into the reciver hitch on my truck and with a 2'' ball to the trailer hitch. see any problems with this set up ??
