Most certainly the small bus is hard to design for , but well worth it in my opinion.
My partner of 20+ years and I live in a 1967 Superior Coach on a Ford 500,
Many of the places we've been able to live or even simply park , would
not have worked with a full size bus. Somehow shorties are cute
We have a kitchen , stove , oven , fridge, satellite TV, internet , telephone, catalytic heater and
soon hopefully a sun-mar RV toilet.( already have the room built for it, just need the cash.)
12 Deep cycle batteries , solar , 40AMP land line charger , 90AMP batter isolator,
and we are in the middle of building a wood gasifier.
One of these times I need to take some pictures of the bus.
