Originally it was probably the prototype of a minibus. Edit:Multipurpose can mean workshop and living area... ;-) Body either from the factory or from Sanok (PL), I can't find any clear information on this. Edit: I just stumbled across answer #27 again. According to this, the body comes from Poland, so from Sanok. Year of construction should have been 1991. The engineering company took it on a trip to Ulan Bator in 2013.
