It looks like it has been, and still is, a bit cold in your area. You write this occurred in January. Where were you camping? The hydraulic fluid is affected by cold weather and causes the pump to work harder which increases the amperage required. The 50 amp self resetting circuit breaker would be my guess as the first place to check as Daryles suggested.
Also call Lippert as they are terrific to work with and very helpful.
I don't know who "they" are that did the diagnosis but to say "the system that had "come apart" and caused something, rubber or metal, to enter the system and that was causing a system overload." is extremely difficult to believe. (please don't tell me it was CW).
On Edit: If "50 amp self resetting circuit breaker" is a new term for you then read this Thread. It should help.
