I can only guess here, as you have no specific rig info in your post or your profile...but:
As for the stabilizer jacks, if they are Lippert units, they are protected by both a fuse (in the power center) and a self resetting breaker (someplace close to the stabilizer, inline with the power feed).
I had my fuse go before my maiden voyage. I replaced the fuse with a self resetting breaker (in the power center), and have not had a problem since. If you do a search here, you can find other threads on this issue.
Glad to hear you had no MAJOR problems on the maiden voyage!
