My mother and father factory-ordered their 1973 31-footer with the mid-ship double bed and the L-shaped gaucho up front. In addition to that, we got the canvas hammock bunk for over my Mom and Dad! Usually, whoever drew the short straw got stuck up over Mom and Dad! Most of the time it was me. I remember stepping on Dad's belly several times in the middle of the night to go to the bathroom!
There was 6 of us then. I had an older sister who slept on the front couch, which does not pull out. My two brothers slept on the side couch, which does pull out.
When I turned 16, my one brother and i bought a 1963
Bambi just to get out of our parents A/S! Man, that was fun!
If you want a 6-sleeper, look for one with the L-shaped gaucho. I have seen a few of them before but they are getting harder to find as they get older and people renovate them.
