Our first Class A was a 27 foot Pace Arrow. The floor plan was absolutely HORRIBLE! Well, let me explain that; DW was working night shift, and when she went to bed, I could not get to the bathroom!
Anyway, we traded it on a 32 foot with rear bedroom, and it was MUCH nicer!
Now, we have the coach in my sig. and are quite happy. DW says it is the last one.
Over the years, I found that one thing to keep in mind is NOT how many the coach will "sleep"; the number of people you can stand to have in there on a rainy day is MUCH more important!
IMO, 30 or 32 foot is a good length; long enough, but not
TOO long!
Have fun shopping, and good luck in your search.
