I have OEM bed cover. I haven't actually tried it, but it would seem problematic to remove the top tailage cap. I wonder what he can say about it?I emailed Jim Martin of Dynalock about the question raised in this thread about what you do if the actuator fails. His reply was to remove the top cap of the tailgate, put your hand in the opening and move the locking mechanism manually. Not a perfect solution, but also not entirely difficult either. Just wanted to let you all know what the current 'conventional wisdom' is on this issue. I can see where installation of a string (as posted by bongus) as an emergency release mechanism might be a good solution. I did not do this and will sleep in that bed when the time comes.
