Hello back from another Southern CA member! While I can't offer any feedback to your questions you might try posting the questions in the forum that is more directed to the topic. Often more experienced members will search for questions or threads there and give feedback.
I do hope you are able to get your unit back in tip-top shape and traveling again.
Great choice for "Living within my means" and camping for one...
