Different strokes for different folks, but i don't see nothing good coming from it. Back trailer in far enough and problem solved. imho.
Backing the trailer in far enough is not always a good option for me giving the condition of some of the ramps I have to use. Due to power loading/unloading and river/stream currents, most of the ramps I use have a huge washed out hole at the end. If my trailer drops off the end of the ramp down into the hole, my life just got more challenging and a lot of folks wanting to launch are gonna be miffed.
