So you drive up (or back up) on these until you are level side to side. Then someone has to slide the second chock in place to hold the whole thing secure? I am confused on how this is a one man operation then, and am also worried about the safety of the person who pushes the second chock in place while hoping nothing goes wrong and the camper does not roll over their hand or foot. I am interested in these but not sure if I am missing something. The way this works in my head does not seem safe.
Edit:
I just watched the video. They must have showed driving up on the ramps atleast ten times. Only once did they show it being chocked into place. The chocking process sure looks dangerous to me. I sure don't want my kid or wife sliding that chock into place while I sit in the van with my foot on the brake holding the camper in place on ramp. Too much oportunity for someone to lose a hand.
