The answer to your question is actually quite surprising. There are some states that do allow you to have passengers in Travel Trailers and 5th Wheel Trailers while they are going down the road. See the lists below. Some states have requirements you have to meet in order to do this so you should check your local state laws for those requirements.
States That Allow Riders In Travel Trailers: Arizona, Indiana, Iowa, Kansas*, Maryland, Michigan, Minnesota, Missouri, Nebraska and North Carolina.
* Some restrictions check state law.
States That Allow Riders In 5th Wheel Trailers: Arizona, California*, Colorado, Indiana, Iowa, Kansas*, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, North Carolina, North Dakota, Oregon*, Pennsylvania*, South Dakota*, West Virginia and Wisconsin*.
* Some restrictions check state law for more details.
Since we are on this subject I thought it would be important to include a video tutorial done by a famous Movie and TV star on trailer safety. You should have a pencil and paper available so you can write down the important safety tips provided in this video.
