We are having Concertone problems with our 07 Cardinal 5th wheel. Have had it replaced once and went to stock up the camper this spring for the summer and once again it won't power up. The last time it happened (last Spring) the tech where we bought it said it had a bad 12 volt plug so he hard wired it. Unfortunatley it worked for the summer but after sitting all winter once again no power! Very frustrating and the more I read about these systems, the less I like it. Also have the humming problem in the speakers a lot. Do you know if I go to the Co. who makes these or Forest River?
Any help would be appreciated
