I have a 35' Winnebago Sightseer with "KWIKEE 3000 jacks. Kwikee no longer makes these jacks and they cannot be repaired if leaking. If you are buying any MH that has these jacks, run away as fast as you can. I am relegated to putting up with the leak, trying to find a used jack or, replacing the entire system which will cost $$$$$$$. Any suggestions.
