Welcome to IRV2, Trigger3lite,
This post is pretty much an echo of other posts.
If you haven't seen it, you should see the movie 'The Long, Long Trailer'. (I think it's a prerequisite)
If your in California, passengers can only ride in a 5th wheel as long as there is safety glass, audible or visual communication between the passengers and driver, and one unobstructed exit allowing access from inside or outside the trailer.
I won't allow anyone to ride in the 5er if we're traveling. Too many negatives outweigh the positives.
Safe travels to you and your family,
