I didn't think it mattered a whole lot but...
When we pull over for a lunch break while traveling DW has full access to the kitchen area including the frig,stove,microwave and sinks if needed.We can squeeze between the slide and counter without any problem and sit at the dining table and eat lunch.The bathroom is upstairs and is easy access since there are two doors so you don't have to go thru the bedroom to get to it.
We bought this Bighorn in 08 and have spent up to six months at a time in it and enjoyed every minute.Wouldn't change anything in it as it suits us just fine.
