I apologize if this has been covered before. I am new new new to the 5th wheel community.l and over 20 years since having a camper in general. My slide out does not work on my csmper and i am looki g for ideas to search out. Ive replaced the switch to operate the slide out just for kicks, also put a good battery in because it says "battery hook up required for slide out operation" i do not get any clicking, or any sound, any slight movement...etc, etc...i get nothing. Can someone PLEASE tell me what else to try or do? Camper is still mounted to truck if that matters.
