I've noticed that the majority of electrical problems can be attributed to rusted or corroded wiring contacts, particularly grounds.

Without a wiring diagram and specifics of the system available, it can be hard to test system components like relays or solenoids.  However, we do have enough electrical gurus and experienced RVers here that at least one or more will be able to help you troubleshoot the system.

I would begin with checking whatever wiring you can find and trace and check for weak, crimped, or nearly broken wires and clean all the connections (particularly the grounds) as you can find.

Another Kevin in the forum.  You'll be challenged to keep up with the other one.  Just reading his posts will tire you out.  But to your MH, I have the same system in my Holiday Rambler.  Sometimes it will growl and make awful noises as it pumps up the system and then the noise stops and everything works normal.  I agree with Mark that it is probably an electrical problem.  It could be at the ignition (it has to be on) or the control box.  You can take out the control box fairly easy and look at the wiring.  I imagine Dave has a diagram of it in his vast library.  If it is an 100 model, there is very little on the internet about it.  Below is a PDF about the control box.

If you would like help on the other issues, like the fridge, use the message search and post on the corresponding boards.  I'm sure you'll find or get the help you need to get it ALL together!

Welcome to the forum!

Anything can be fixed with enough time and patience, although sometimes parts need to be replaced.

If you do decide to sell your rig, sell me the levelling jack system...lol!  I'll pay good money even if they aren't working!

Anything yet kpq?

I forgot to mention that on my RV I had a small problem with mine as well. Turned out my batteries were weak because my alternator was not hooked up right. When my engine is running however, or the batteries have a full charge, the leveling jacks work great..
