MacJack, I assume that, by valences, you are referring to the little cloth drapes that run across both ends of the camper, covering up the roof hinges? If so, you should know that this is a problem that has been commented on abundantly. After doing all kinds of fooling around trying to get mine to stick on the A122S, I finally gave up and put little screws gently through the top of the drape in several places across the width of the trailer. That took care of the problem. Don't waste time fooling around with the velcro; it's useless, especially if you store stuff in the bed area during the day. Every time you store something up against the drape, it puts downward pressure on the velcro, pulling it loose eventually. You won't even notice the screws once they're in place and the drape won't come loose anymore.
