Are you positive it is not locking? This is from the Blue Ox web site instruction manual for the alladin:
"In normal straight line towing conditions, both legs will be in tension. Due to the design of the latch, both handles will feel loose. During turning, braking or parking one or both of the legs may be in compression. This will make the handles feel stiff or tight. Due to parking on slopes or the angle between the coach and the car, the two locking mechanisms could be in compression or tension or any combination of the two. Having one lock in tension and one in compression may give
the operator the feeling that one leg is locked and one is not, when in fact whenever the legs are fully extended and the springs are holding the latch handles up, the legs are locked and ready to tow whether in tension or compression. "
If you are sure you have a problem give them a call, they have a maintenance program where you send your bar in for repair and they either fix and return or give you the bad news that is not repairable.
