I don't have a roller trailer but I can imagine trying to drive it on the trailer up a steep boat ramp all alone could be a problem. As a matter of fact I have seen a guy w/ roller trailer at a ramp start backing down after un hooking at the bow loop only to have the boat roll right off the trailer!!!!!
My 21'er is on a roller trailer... I rarely power load the thing, but still do minimal winching. I back the trailer in so that the back set of rollers are just barely breaking the surface of the water and drift the boat on with the help of a looong rope. I get the bow within a foot or two of the winch, hook onto the bow eye and in just a few cranks its tight to the winch stand. Quick and easy, even when I'm alone.
I was always told you should take no more than two minutes at the ramp. That time limit helps keep the line moving along and no one gets testy. LOL. I would think an electric winch would slow the process down instead of speed it up, no?
