A travel trailer is like a little house on wheels that people can use to travel and stay in overnight. It usually has a small kitchen, bathroom with a toilet and shower, a bed or two, and a small living area. It is different from a mobile home because it is much smaller and meant for short-term trips. It can be towed by a car or truck, and parked in a campsite or RV park. Some travel trailers also have a pop-up feature where they can expand or extend to make more space when parked. It’s like having a portable home that you can take with you on your adventures.
