A recreational vehicle, or RV for short, is like a big car that you can live in and take on adventures with your family. It's like a home on wheels with everything you need, like a kitchen, toilet, bed, and sometimes even a TV.
Just imagine going on a long road trip with your family and bringing your home with you, too! You can park your RV in a campground or near a lake and have all the comforts of home while still enjoying the great outdoors.
Some people even use RVs as their permanent home and travel all over the country, seeing new places and meeting new people. It's like having your own little house on a big adventure!
