i think you are putting too much throught and effort into it...we used to launch out 27 ft fountain with a 2wd ext cab chevy..just put it in reverse, back down the ramp, and put it in park when you get to where you need to be..back the boat off...loading do the same..back it down the ramp, load the boat on the trailer, and put it in first and pull up the ramp..
