Big Roy why do you need 2 people to fit the alko secure I can do it on my own dead easy, chock the wheel with a bit of wood, leave off the handbrake,move the chock whilst turning the wheel/pushing the caravan,until it line up.
Note this unit is far superior to any other wheelclamp on the market.It is well worth the effort to fit it. I could remove any other wheel clamps in under 5 mins with my Dewalt 18v angle grinder. The Alko would take great effort to remove it. GS
