our old coach had the drop down overhead bunk. We used it once. Here's why: most adults won't climb up there to use it. Most kids like it, but then you have to worry about them falling out of it at night. It takes up A LOT of room and seating area unless you raise it every morning after use, BUT ALL the sheets, blankets and air mattress have to be removed so that it will fit back up against the ceiling properly which means remaking the bed every time you use it. Also the motor and track used to raise and lower the bunk was kind of tempermental so you run the risk of it getting stuck in the down position making the coach inoperable until a mobile tech can come out and fix it. Our old coach was a THOR Palazzo which was a VERY unhealthy coach! 7 times in the shop in 18 months of ownership really didn't make that drop down bunk worth all the headaches!
But if you absolutely have to have the drop down bunk, yes the Forest River Legacy is your best choice. Forest River makes a very well built, sturdy coach.
I would suggest you look at one of the Forest River Bunk models. The Bunk sleeping space is MUCH more usable for every age group and the doors across the bunk area make it so you can close it off during the day and keep the "guest clutter' out of sight.
Good Luck in your RV search
