YouTube is your friend. Even without YouTube RVs are fairly simple beasts & whipping out the credit card & heading for the dealership should not be the first option in repairs.
I came from the boating world. 30 years worth of self taught self maintaining much of it well before YouTube. The last boat was a 32' single diesel with a 6KW genny & all of the electronics expected to be found on a boat that size. Much more complex than the RV so the change to RV was easy.
Everyone should carry the basics in spares, have better than the basics in tools & know how to use them. Saves lots on money & aggravation when you can fix the small stuff yourself.
