Just want to say thanks to all the folks here who responded to my post with encouragement and advice. Though I've been researching this entire matter for several years now, there's no better teacher than hands-on experience. Though I'm very good at fixing things, I'm learning that there is much going on in these RV's that I have no experience dealing with. You'll probably be seeing my posts over and over again as questions pop up (though I'll try to research past threads for answers to my questions).
Thank you again.
Steve
