I just bought this RV and found out I had to use an air tank to activate the two slides as the Air Pump (compressor) does not work. My problem is that I can't find a dealer who handles this item or even give me advice on what to do. Can someone tell me if I can use any 12 volt pump with at least 4 cfm production to operate the slides. I guess better than that can someone tell me where to order the original pump? Thanks ahead for everyone's help! Mediocrity is not an option!
