Speaking of floor plans; here's the most recent revision to ours for our new Thomas Safe-T-Liner.
It's a little hard to read but I didn't want to make it too large; here's the link
for the bigger version.
This is a flat-nose transit style bus (36' overall) and has wheel wells forward and aft to contend with; they dictate a lot about how the interior can be arranged. In the Thomas they're about 24" wide, about 48" long and 9" high at the top of the curve.
This is also a rear-engined bus so the area behind the bed is part of the engine compartment. The rear seat is also part of the engine compartment but since it's at a standard seating height it's used to support the rear of the bed.
Our primary design goal was for a comfortable bus for two folks for extended trips and full-timing. Our version of a Wanderlodge if you will. My wife also is an artist (painter) and plays the piano (very well and I love to listen) so that had a large impact on the design.
When coming aboard there is a swivel seat immediately to the left which is the co-pilot seat underway (there's a cover over the stairwell) and a comfortable lounge seat when stopped. It sits just ahead of a 9" high "floor" over the front right wheel well; on top of this is the cabinet that holds the main TV, a small bookcase and a wine rack. At the aft end is also where the Dickinson propane marine fireplace resides (it's a direct vent unit that's there for ambiance and a back up source of heat).
Aft of the driver's seat is an 80" couch (over the left front wheel well) that pulls out into a double bed. In front of it (toward the centerline of the bus) is a pedestal table. The Roland RD-700X Digital Piano is mounted on a base plate installed at the top of the pedestals over which a "box" fits which then becomes the table top. The top is lifted out of the way when one wants to play the piano. The top, the piano on its base and the pedestals are all removed to form the bed.
Aft of the living room area is the kitchen/work space. On the curb side of the bus it's easy to see the sink, range (with micro hood over), and refrigerator. On the driver's side just aft of the couch is a counter which holds our espresso machine and coffee grinder (hey! we're northwesterners!), aft of that is a 48" long desk/work table, and aft of that a 24" wide storage cabinet. The main electrical panels, tanks monitors, genset controls, and such are mounted in the top part of this cabinet.
Next aft is the bathroom area; the door to the toilet room swings around to close off the bathroom and bedroom from the forward part of the bus which really makes the bath and bedroom one large dressing area.
Since this will be a full-timer I worked a small but reasonably sized bathtub in; we won't use it often but on occassion it will be a treat to soak in the tub.
The toilet lives in its own private room (mostly to keep the passageway of the bus open even when it's in use). It sits in front of the existing emergency door which is still usable should the need arise.
The two closets in the aft part of the bathroom are placed over the two rear wheel wells. An LCD HDTV is mounted on the rear side of the curbside closet for watching from bed.
One of the things that I most wanted to incorporate into our rolling home was a large bed. We're used to sleeping on a king-sized bed (along with our two Blue Heelers (Australian Cattle Dogs) and I wanted that same level of comfort in the bus since we intend to be in it full-time at some point. There are narrow cabinets (about 7") on each side of the bed for additional storage, a place to set a clock, glasses, water, tissues, etc.
Aft of the bed is the "deck" over the engine. At its aft end is an existing emergency window and we decided to keep that for light, ventilation and emergency egress if we needed to bail out. Small cabinets are in each of the rear corners and they also house the reading lights.
Since the bus has limited headroom (6' exactly) there are mini-split air conditioners mounted forward in the center over the driver's area and at the far rear over the engine compartment. Just like with house central air the main (compressor/condenser) unit is "outside" (in this case in the storage compartment under the bus) and only the air handling unit is mounted inside. This alleviates the need for roof-top air and that units register/control housing's intrusion into available headroom.
That's about it...thanks for looking.
