We love our hybrid. I love how much air flow and light we get through all the windows. We like the tent feel with the comforts of a TT. We have camped in 20F weather and in 95+F weather with no issues. With hookups, the AC will freeze us out of the trailer.
When we moved from a popup to a hybrid, we had a 13 y.o. boy and a 9 y.o. girl. We decided we wanted them to have their own space. That lead us directly to the 3 bed hybrids. We ended up getting the Rockwood Roo 233S. We love this camper. We have 3 queen beds and my daughter loves the privacy of the back bunk.
I believe that most of the brands have hybrids with 3 bunks.
