Alas, not very far. All of the original wood closets, cabinets, chest of drawers, bed or dinette frames, etc. were long gone. The only portions of original interior remaining intact were the stove, the stainless steel and aluminum sink cabinet, and three overhead aluminum cabinets with wood doors. The stove and sink were in a common position in virtually all of those floor plans, and the position of the overhead cabinets were not indicated in the plans at all. Window positions might have offered some clue, but the actual window positions on the trailer don't exactly match any of the plans.

The 1949 brochure shows three variations each for the front and rear portion of the plans, for a total of nine possible plan combinations. But all of those combinations result in a area at front that could sleep at most two, in a bed no more than 46" wide. Great for a single person or a couple, but most of my friends of either sex are single - not cool if I want to bring more than one along.

With the one single bed approach, I'm back to the problem mentioned earlier, of only having the one additional spot to sleep. However, it can easily accommodate another on an air mattress at the foot, or two on two different sleeping pads. The two beds variation looks like it might be a bit cramped, though. I'm not sure.

I've cleared up some of the mystery in terms of possible floor plans, narrowed down my own choices of which to choose from, and figured out roughly what carpentry will be required for the interior. That probably enough on this topic for now.
