Books for first time RV owners?

Most of the rv stuff is not that complicated. Help them buy a set of basic hand tools and show them how to replace a tire. I barrel jack is really handy if they have a trailer. Rv tire changes are a little different than on a car. Mostly get them to understand that if they don’t get scared of a problem and think they can’t handle it, just stop and look at it and think it through. They can probably do more than they’re giving themselves credit for.
They also might enjoy a subscription to trailer life or motor home life magazine. There are some informative articles on maintenance and just plain fun stuff, especially for a beginner.
I hope they enjoy the new toy. Happy Travels!!!
