I take everything off the mast except the main halyard and I use plastic wrap and duct tape to secure the rotator arm and the down haul cleats
The plastic wrap with a hand full of wraps is surprisingly strong. I've never had any trouble with it coming lose. I like that it keeps the road grime off the mast too
My set up time is about 2x with the mast fully rigged but it's much less worry when trailering. It was such a head ache to make sure all the rigging wouldn't work lose on the road
Here's a pic of my mast base before loading the mast onto the trailer
