What is a home? A home contains:

• Bed
• Bathroom
• Office
• Kitchen
• Laundry
• Storage
• Garage

I wouldn't move a lot. I could stay in one place for a week or a few months. The point is the ability to take your home with you and live wherever you want.

A motorhome or a trailer? I don't see the point of a separate car or tow vehicle. If I need to drive to the city, I usually stay in the city for a few days, so may as well take my home with me.

For nimble mobility I could have a motorcycle, or an electric bicycle/motorcycle. The motorcycle can be stored within the motorhome in a mini-garage.

What you give up is having a big open space, and private spaces when having guests.

Apart from satisfying all the needs listed above, specifically the following:

• class c with overhead bed
• composting toilet
• washing machine and separate clothes dryer
• shower with heat lamp(s)
• solar panel array on roof that can be stowed for travel
• reflective solar concentrator can be mounted or extends from roof
• redundant heat energy storage like butane
• uses the air conditioner running from the engine
• scenic windows that can be blocked with slideout reflective material
• indirect ambient lighting

Class C because the only thing I need a bed for is sleeping, and what better to have underneath the bed than seating, with swiveling captain chairs.

Behind the front seats, modularity should be a design goal so that the space inside the home can be organized as needed. The walls and floors could have adjustable connection points for any module such as storage, tables, sofa-bed, etc.

Even overhead storage could be modular. What kind of securement would allow quick release and gliding along the ceiling?

The kitchen, bathroom, and laundry probably needs to be stationary due to water and other connections.

A retractable table behind the swivel captain chairs, along with a sofa makes for a good office/dining area. A computer screen can fold down from the ceiling, rotate 360, and even swivel to the wall.

The driver and passenger doors are sufficient? A side door probably isn't needed. The back can have a tailgate.

Can the composting toilet be in the wet bath? Can the composting toilet be easily moved/modular?

Can an outdoor area be added to the living space with a tent?

A kitchen section that can easily be extended, swiveled, or moved outside so on hot days the heat from cooking doesn't add heat to the interior. Maybe not worth the complexity. I don't cook much. I can cook meat in large quantities, and store in a frige/freezer.

I may be able to fit all this into a 19-22 foot class C motorhome.

I don't want to carry that much water, as it's heavy. With heating lamps surrounding me from all sides I may not need to run the water continuously to feel warm. The heating lamps will use less energy than heating water.

A reflective solar concentrator in principle can be used to heat interior (shower or main space), to drive air circulation, as a solar oven, or wherever heat may be needed.

Battery for solar also hooked to the engine alternator for backup charging.

Plumbing should be freeze resistant.

Air quality sensors.

To simplify by not adding an additional system, use the air conditioner that's powered by the motorhome's engine. I don't mind having a redundant heat source like a butane canister because it is simple, compact, and low cost.

An interesting idea I probably wouldn't implement is a wood stove.
