Boat trailer

I doubt that would damage the axles. My concern would be tread separation on the tires - they aren't made to move like that.

I am not a thief, but I don't understand how pulling it sideways would get it to release from the truck. And, if they were trying to steal it, and got the lock off, what stopped them from taking it?

I've heard of tires/wheels stolen at the ramp (my folks had that happen), but never the entire trailer.
