Does anyone out there have a Big Country 3596RE? I am looking for specific information on how to manually override the hydraulic landing gear and slide rooms in case the systems fail. We are leaving Delaware and driving to the Grand Canyon soon and we just want to be prepared for the worst. Our RV is a 2014 but even new units can have problems. We contacted Heartland and got generic answers that don't work. We contacted LCI who designed the system, same thing, generic answers that don't work. We went to our dealer where we bought the unit. They were stumped. I hope we never need to use the override but we would like to be prepared in case we do. Any help out there? It would be greatly appreciated.
