Here's the thing....you won't really know what you want until you have been in or using one for a while. We thought we wanted a bunkhouse when we bought our TT. We figured my daughter would bring friends. After 3 years, not one friend came along. A waste of 7' of a 31' trailer. We learned to not like the short closets. My shirts would bunch up at the bottom of the closet. I'm only 5'9", so my shirts aren't very long. That was one thing we wanted different in the MH. We also learned to not like our bed. Ours was like one of the TT you looked at while at the show. The bed was the entire bedroom from head to foot with walkways on both sides. Ended up being a pain in the butt.Especially if only one is making the bed. You just can't go around the bed. You have to leave the bedroom, go through the living room to the other side.
Don't expect to get it perfect the first time. You will learn what you like, don't like and can live with out.
