Just used my Lock’n’Level for the first time. I thought a quick email to say how pleased I am with it. It was simple to use and solved a problem I have been toying with for some time. It also saved me £160 on my caravan insurance this year as the caravan club insurance would only give the wheel lock discount when both locks are fitted. I have been unable to get both locks on because of the problem every twin axle caravanner has of the jacking points being removed to enable twin movers to be fitted. So the cost of the Lock ’n’ Level was recouped in one year. Thanks for a great invention.
