Well, I got about the first 40 pages of the owner's manual. The fellow with the black '73 (I haven't mentioned his name, since I haven't asked his permission to do so) snapped pics and sent them to me. The rest will be coming when he finds some more time. I am very appreciative. I think he said his manual is actually for a '72.
I've already discovered quite a bit of interesting stuff. For one thing, the fridge isn't 6 cu'. It's 7 cu'. 6 was standard, 7 optional.
And, Norcold has a 7 cu' ac/dc fridge.

I haven't taken measurements yet, but I imagine the Norcold will be pretty much a direct fit in the hole where the Dometic is now. The specs say it draws 3.2a at 12v. The question is duty cycle...just off the cuff, at say worst case 50% duty cycle, that'd be 3.2a x 12hr/day for about 40ah per day. With 300w solar, MPPT, and 400ah of battery, I can easily live with 40ah/day for the (7 cu'!!) fridge.
(And I can re-task that propane line, for either a cat heater or a Propex. Yay!)
I know what that missing cabinet in the right rear looked like. Half a closet.
And what's that I see bolted to the side of that cabinet? Why yes, it's the thermostat for the furnace. No wonder I haven't been able to find the friggin' thermostat, there ain't one. I think that also explains the pair of low-voltage mystery wires that poke out of the wall near the 120v breaker box. Halfway down the wall, to the left of the breaker box, wrapped in black.
The MonoManiac toilet IS rigged to dump into the holding tank. And a question I was wondering about answered...
Q: When you fill it using the water valve, how in hell do you know when to stop? I mean, I don't see any way to measure 4 gallons...
A: It makes a different noise.
I'm guessing once the water inlet is submerged, it's done.
"When the toilet becomes full after many uses..." Many uses. The docs I saw said around 80 uses, but didn't specify 80 #1s or 80 #2s. I'm thinking, if I'm full-timing solo, dump it once a month maybe? Dunno. Also, going to have to find a source for blue juice additive. Hopefully, some sort of organic or at least non-global-warming-inducing-and-ocean-adicifying chemical. Provided of course, that I can actually get the MonoManiac up and running.
There is more to that master control panel than meets the eye (thought there might be). And mine does not have the optional barometer and clock (would be on the side of the fridge cabinet, up high).
And, I now have a little better idea about that water system. First, a 30g tank was standard on the 2200, 40 on the 2500, but the 40 was optional on the 2200. Here's what the standard 30 looks like:
So I'm pretty sure mine with the oddball double tank arrangement, is the optional 40g setup.
AND!
Mine seems to be a bit different. For one thing, I remember a different sort of pre-filter for the pump. But mostly, it's exactly what is described in the manual. Three different drain valves, and the whole works sloped for easy draining for winterizing. Nice.
Other things I discovered...
The cane insert cabinet doors were optional (mine has them).
If you have the optional water heater with an engine coolant loop, there is a shutoff valve on the dash (haven't looked yet to see if mine has that).
Each windshield wiper has its own switch. But only one (separate) push button switch for the windshield washers.
There were two rear compartment layouts. One (which mine has) had two twin beds. The other had a "gaucho" couch on the right side that folds out into a double bed, and a chest of drawers on the left side.
Over the cockpit, a storage shelf was standard, the drop-down bed (which mine has) was optional.
There were two A/C units offered, 10k BTU and 12k BTU. Mine has the 12k.
Seems like the double galley sink was standard. The sink covers flip over to become cutting boards. (Gonna have to study that long and hard from a sanitary perspective before I even think about actually using them that way.)
That's about it until I get some more of the manual and make additional interesting discoveries.
Picked up the new spark plugs today. They didn't have the plug wires, had to order them from the warehouse. Supposed to have come in today, so hopefully I can pick them up in the morning. Just as well, I forgot to get a new ballast resistor. Hoping to finish the ignition tuneup tomorrow. O'Reilly's database shows the Dodge M300 chassis, but only shows a 318 engine for it. But they figured out a way...look up a '62 Chrysler Imperial - that shows the 413.
