Here's a good article, pros and cons, as I've never owned one. But I have owned a pop-up and a hard sided travel trailer. And I've looked at many of them at dealerships, even considered one when changing from the pop-up to the hard sided trailer.
Click here.The biggest disadvantage (in my opinion) is the challenge to use one for winter camping. As the article cited above says, hybrids are good for fair weather camper.
The biggest advantage (in my opinion) is the shortened length when closed, and the expanded length when open. Also, if you enjoy tent camping, this keeps the feel of tent camping, with the comfort of a trailer. But that also is a disadvantage, because in a tent you can't block out campground noises, in a closed trailer, you can (to some degree). And, remember, if you can hear "them" outside the camper.... "they" can also hear YOU inside the camper! They lack privacy. (That's a disadvantage).
