I have a 1982 Holiday Rambler Imperial 30. We went on vacation last week and blew a hydraulic hose, for my leveling jacks. I went to the local parts store and got stuff to repair it, I didn't loose much fluid but I need to refill it. We found information on the type of fluid that it takes, but haven't been able to locate where to refill the system. Any help would be appreciated. thanks.
