After weeks of chasing intermittent level up and slide out operation, finally found the problem with the help of an ace technician who rescued us at the Canton/East Sparta KOA in O-hi-O......the three bolts on the hydraulic pump solenoid were loose, causing voltage/amperage fluctuations which kept changing the symptoms
Searching the forum for a thread on this fix didn't yield anything, so I thought I'd share....sorry if it was previously discussed and I missed it, both for annoying you for a redundant thread and me for the cost of a service call....
