Maybe I missed it somewhere in this thread, but what do you plan to have along the side aisle in the middle, versus in the centered portion? Bathroom in the middle, I assume...kitchen as well?
gwreddragon, I'm planning to leave the original (structural) floor exactly where it is, although I do plan to improve the insulation. I want a side aisle down the curb side, and really would like to have a lot of visibility out that side as well.
I plan to raise the roof 30" to 36", bringing it to a total of 12'6" to 13'0" at the tallest spot. That gives me 6" to 12" of room for "stuff" that I haven't figured out yet.
I plan to build up a secondary floor 18" to 24" above the original floor. This would clear the wheel wells completely, and provide me with a lot of storage for tanks, etc within the main thermal envelope. This will also help keep the center of gravity low. Above the drivers area, I want to build a loft. I want to treat the main entrance and drivers seat area as an airlock or "arctic entrance" like is used in Alaska. I want the main interior to be well insulated. The drivers area will also be insulated, but unfortunately, I won't be able to be as thorough in that area (big single pane windshield, pedals, etc).
At the rear of the bus, I plan to have a a very small room above the engine's highest point for tool storage. I want to have a passthrough so that I can escape the bus that direction if needed. The bottom of the room will be above the engine access panel, so it'll be quite a ways off the ground.
The rest of the engine covering area in the rear will be inside the bedroom. I want either a queen or king sized bed, but haven't figured out that detail yet. It will need to be movable so that the engine service panel can be accessed.
Forward of the bedroom will be the bathroom. I'm hoping to be able to squeeze a real tub in there, but I'm not sure how I'll accomplish that yet.
Forward of the bathroom will be the galley. I'm not much of a cooker, so it will be a small galley. My hope is that most of my cooking will be done outside, on a grill. I do plan to have a propane stove/oven, a microwave/convection oven, and the main sink in the kitchen.
Forward of the galley will be the living room area. I'm still not sure how that layout will end up being.
The bathroom and rear bedroom will have privacy doors. There will be some kind of door between the living room and the driver's area. The loft will probably be just curtained off, but I'm not decided on that yet. I want a small skylight in the loft so that it can also be used as a reading nook.
I'm considering having the rear bedroom be down at the original floor height so that I could put in a ceiling fan if I wanted.
I plan to keep my original curved roof. I plan to steal Smitty's "truss" idea for the interior.
My heat plans are to have everything be hydronic. I want to have multiple heat sources (solar, engine, propane boiler, and diesel boiler) and multiple heat load zones (engine, different room zones, and a few forced air heat zones, as well as the drivers area, and keeping the fuel tanks from getting too cold).
I'm considering installing a basement type A/C unit.
Beneath the original structural floor, I plan to have the remaining essentials. Those include the battery bank, generator, extra fuel tanks, propane tanks, and some exterior access storage.
All tank drains and power inputs will be kept on the driver's side of the vehicle.
For food storage, I plan for some of the space between the two floors to be used for dry goods storage. I also plan to use small chest type freezers for both frozen foods and as a refrigerator (using a thermostat to turn off power to the freezer to keep it above freezing).
I want a very large water tank, and reasonable sized grey and black water tanks. My main water tank will be considered non-potable, so I can refill it from a river or lake if necessary. I'll have a separate potable water storage.
I have a lot of plans, and a finite space, and so there will need to be compromise.
Anyway, enough babbling for now. I'll be happy to answer any specific questions.
