I'm a new owner of a '72 13' Trillium
. While I do my camping alone, for the most part, there may be times when I have company. My unit doesn't have a front bunk and I can't see where one may have been installed. Did this unit originally have a front bunk above the front bench seat/bed? There seems to be room for one. Perhaps a frame installs on top of the bench to support one? If someone can point me to pictures or offer advice I'll appreciate it. Hopefully, (one day...) I'll have grandchildren to share a camping trip.
