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.

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

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 could have adjustable connection points for any module such as storage, tables, couch, etc. The kitchen and bathroom probably needs to be stationary due to water connections.

A retractable table behind the swivel seats, along with a sofa.

The driver and passenger doors are sufficient? Is a side door needed?

Can the composting toilet be in the wet bath?

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

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 don't want to carry that much water, as it's heavy, but maybe I have to? With a tall heating lamp or a set of heating lamps mounted vertically along the shower wall, I may not need to run the water continuously to feel warm. The heating lamps will use less energy than heating water.

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

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 of the simplicity and low cost.

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