I just did a search and it comes up as a 5th wheel and he did say it was.Correct me if I'm wrong, but isn't a Cougar 24RDS a pull behind camper and not a 5th wheel? If it is then there should be zero discussion about what state this is legal in and what states it isn't. This type of combination is illegal in all states, as it should be (unless something has changed in the past 10 years).
Now if you had a 5th wheel as your initial trailer and then a ball hitch on the back of that you would be legal in some states, depending on your total length.
