I have a 2005 Dynamax Isata 282SL 29 footer with HWH kickback hydraukic jacks. 8 times out of ten, the jacks work perfectly.
However on the other two occassions (average), when I hit the "On" or "level" button on the touchpad on the dash the system fails to activate. Yet, after a while, the system turns on fine.
When the system does come on, it works perfectly. I cannot relate these intermittent failurs to any othe source (weather. gegree of level of campsite, distance traveled that day, etc.)
On my previous Mh I had the kick back HWH levelers. They would sometimes fail to operate. It was usually when it indicated "Low Battery". The indicator is located on the operating control panel for HWH. When the batteries were low the light was dim and difficult to read. After I would charge the batteries they would work.
Also, after I cleaned the battery terminals and the cable terminals the events were less frequent.
