I'm with you, eskins. Same here with a strong electronics/electrical and handyman background, my first RV really threw me for a while. Eventually, just dug into it and ended doing 90% of the repair work myself.
Usually, I'd find some help here on this forum, then dig into the problem. With your step issue, for instance, first thing I'd do is just crawl under there, disconnect the wires, then the throw arm. Using heavy duty zip ties, lash the steps up in the closed position. (And use one of those plastic steps to get in and out during the interim). And continue on traveling.
When I got home, I'd remove the steps and do a full service on them. Great way to learn all about them. Pretty soon, you're an expert.
Good luck, and have fun!
