Wearing seatbelts in RVs is one of the most hotly debated topics in RVing safety. Manufacturers don’t have to follow the same strict guidelines for seatbelts in the rear of a motorhome as they do for the front cab area.
Although you can legally ride in a towable RV in some states, this isn’t something you should do. It’s safest for passengers to sit in the tow vehicle.
All states require the two people sitting in the cab to wear a seatbelt. New Hampshire is the only state that has exceptions, but it’s best to follow this law no matter where you drive.
