Best of luck in your new lifestyle! It sounds like you're a very concientious person who knows what to check mechanically. I think you'll do just fine. Make sure your tires are in good condition and check the date imprinted on them to see how old. You said the RV was stored for 5 years but even if the tires weren't driven, they still deteriorate. If they're older than 8 yr. it's recommended to replace them - and an earlier age if they looked cracked. Do come back with more specific questions. We'd all be glad to help!
