USA Clark, I agree with you completely. We are retired "Baby Boomers" or empty nesters or whatever people of our generation call themselves and we too wanted a camper suitable for two people to camp comfortably in a reasonably small camper. We settled on a Fun Finder 210WBS. For some reason Fun Finder no longer makes that floor plan in the Fun Finder line but an almost identical floor plan is available in the Shadow Cruiser line. I think the Sonic floor plan recommended above is a real nice unit. I wish it had a slide (ours does and it makes for a much roomier interior.
I do like the idea of a Murphy bed. I wonder how practical it is to fold it up when made-up with sheets and blankets, etc. Can the pillows fold up inside also? Perhaps someone with a Murphy bed will read this and comment.
I have made a number of mods to our camper that improve its organization and functionality; you can view them
