Rebecca, I wish I had something beneficial to offer. I have the same coach and are new to Class A DPs. We have owned the coach for one year and we experienced an extremely rough ride after our second trip out. Took the coach to a local CAT dealer who pointed out the exact problem you have, rear jacks extended and would not retract. They bled the lines and were able to retract the jacks. After a closer inspection two jacks (one front and one rear) were leaking and the other two were probably close to leaking as well. CAT found a shop in Jacksonville to cut them open and repack them. During the six-month ordeal the shop ruined the jacks and found replacements (verified with the CAT dealer). The new jacks were installed each with a new jack mounted switch and all seems to be working for now. We are off on a trip on the 18th so we will see.
I am only sharing my experience as I have not seen any mention of a leveler switch in the previous postings. Not sure if that should be considered or not. By the way the wrong switches were initially mounted to each leveler. Either the switch was a normally closed switch and it should have been a normally open switch or visa-versa. The correct water tight switches were installed.
Not to minimize your predicament which is most important to you now, but I'd like to keep up with you and Ed since we have the same coach to understand your experiences.
Best of luck!
