No ground clearance on van, gona get stuck in the mud. less payload on van, can't just drop a skid of what ever or extra long things like hydraulic cylinders into a van with out akward fucking around. less tow capacity on van, notice the tow bar on the back... What are you gona put a welder, diesel cans, gas cans, pales of hydraulic oil for equipment/ slip tanks, pumps and what not into the van too with the occupants? What about the greasy and oily ass clothes. Throw em in the van too? So they stain and fill the cab with VOCs?
This is a purpose built one off, and alot of you are out of touch with how work gets done. Not evey job is hauling standard 8x4 drywall. Alot more trades work than just slinging plaster around.
