I also have a cox trailer under one of my V-20's and I did the exact conversion with bunks AWESOME. Don't take this the wrong way but you found Genie Aye exact trailer conversion on his old thread. That is the same picture on the new thread by Orlando (More Trailer Advice). Some bunk trailers have a tilt pin at the front main beam its only about 4-5 inch' chain to make the trailer bed tilt down for loading it will actually put it down to the ground in most case's. For any long time storage of a boat on a trailer I always go with the bunks,  like Genie Aye said about towing long distance to go where the fish are bunks are best.   Now that is Hard Core Fishing.
