Coinsidenly,I went to look at a 2009 Safari Simba yesterday with the Lippert system. When we went to stow the jack to take it for a ride the jacks would not come up and the control panel was flashing. After multiple tries I told the owner what you all posted about the leaking o ring and I could see the motor covered in hyd fluid. You could smell the motor burning after a while. I really like the MH but it had other problems also and roof which was one piece fiber glass not maintained well and leaked.
