Congrats on the new to you coach! Hope you have lots of fun with it.
One thing that has proven to be very beneficial, to me, has been to spend time with the various owner's manuals. Hopefully, you received them with your purchase. If not, you can likely find manuals for the various equipment through an internet search. Things like your refrigerator, water heater, furnace, etc. are often available for download in .pdf format. Save those to a laptop and when you're winding down from other chores, spend a few minutes just going through them. When (it been my experience that it's a "when" and not an "if" kind of thing) something stops working the way you expect it to, being familiar with the owner's manual can point you more quickly in a direction that will solve your challenge.
