Recreational vehicles, or RVs for short, are like big cars that you can live in! They are mostly used for going on vacations or camping trips.
Think of an RV like a big house on wheels. It has everything you need to live and sleep in. There's a kitchen with a stove, sink, and refrigerator. A bathroom with a toilet and shower. And places to sleep, like a bed and couch.
RVs also have things like electricity, running water, and heating or air conditioning so you can be comfortable inside no matter the weather outside. Some RVs even have TVs and other fun things to do while you're on the road.
They come in different sizes and styles too. Some are smaller, like a van or a truck with a camper on the back. Others are bigger and look more like a bus. Some people even customize their RVs to make them unique and personalized.
All in all, RVs are a fun way to go on an adventure and have a home away from home!
