Holiday Rambler leveler issue

I have no idea how much or how little the OP may be incline mechanically. However he did know to just push the cyl. up so I would think he can do a little to help himself. First loosen the hose on the top of the cyl and see if the cyl goes up. If not then help it up and see how much effort it takes. If great effort it probably is cyl. If little effort it Probably is the springs. If cyl. goes up with loosen hose it may be in the solenoid. To ck. that just swap the left one and the right one and see if it goes up. If so its the solenoid. From my experience working on them.
