I have a 16 Jayco Whitehawk 24mbh that has been a solid camper. I have a 7,4 and 5month old, that loves it. the couch/Murphy bed works great. Bed is A tad small for me (6’4) but not as bad as others I tried, But The Murphy bed works with the slide in and it’s not too bad to get past the slide to get to the back of the camper. it has a good amount of storage space, But I added more under the sofa and outside kitchen
that said I see they changed up some for 18 and it’s missing the small wardrobe and bathroom tub and the outside bathroom door.
Maybe look for a 17 leftover
