In a previous toy-hauler trailer, I did a similar setup but with a couple of different ideas.
- Welded a steel tubing frame (about 12" deep X 5' wide) that held both the winch and the front tire wheel chock for the motorcycle. This clamped down to the trailer tie-downs and could be removed when not needed.
- I used a 120VAC (not DC) winch that plugged into one of the 120v receptacles in the trailer. To use the winch, obviously I had to start the built-in trailer generator. https://www.northerntool.com/shop/to...SABEgJRLfD_BwE
- Just hooked the winch to the lower frame of the trike by the riders foot rest and pulled it right in - slick as all get out.
I liked this setup because it was light enough to move/remove when not needed. While camping I just put it under one of the fold down garage couches where it was not under foot.
In our current toy-hauler trailer, I have this left-over 120VAC winch mounted to the floor along the side wall near the back of the garage (where it will be under one of the couches). The cable comes out to the center of the trailer to a snatch block redirecting to the very front of the garage with another snatch block redirecting the cable straight back and down the ramp and out the door. The idea is if my SxS is dead, I could still winch it into the trailer to get it home. Doubt I will ever need this, but I had the parts so went ahead and set it up. I wouldn't recommend spending the money to set this up for a side-by-side unless you have some specific need.
