Just put your transfer case in neutral and slightly apply the parking brake, you can then stand in the front and make sure your drum is winding evenly.
I just don't rig mine out until I am going somewhere I need it. Rotopax, Krazy Beaver, axe etc stay in the garage. Odds are I wont need them driving to the grocery store or shop.... When I do rig it out I have a couple Bolt cables I use to run through the handles and mounting plates...
