[page to be repaired - add textbar "self propelled and standing height inside"

Anyone with a permit B can drive a modern van as long as it is below 3500 kgms weight.
Like the VW Transporter, Mercedes Benz Sprinter, Renault Master, Peugeot Boxer etc.
They last long and secondhand ones make affordable makerspaces.

For working inside you will need standing height. If you start from scratch, the purpose of the van will determine its interior.

The same criteria apply as for the big trucks: two spheres inside, a fixed lasercutter, put the rest in cabinets on wheels.
CESI in France has a mobile truck to promote the fab concept.

Standard interiors of vans like syncro-systems are more for contractors and jobbers on the road, but you can learn from them. But contractors hardly work inside the van.

A fine example is the SPARKTRUCK, that toured through the US.

The TESLA TRUCK is in the same category

One can just work inside the MAKERBUZZ, but it extends to the ouside world

The MAKERMOBILE accomodates 10 students in a more classical way inside,
primarily aimed at electronics. Note the transparent roof and the tube storage on the ceiling.

On the low ceiling end is the MAKERBUS. A vintage Volkswagen bus, that in 1971 not even could dream ever carrying a lasercutter and a 3D-printer. You can sit inside, but hardly stand up.
So you need the outside world.
