It's based off a vehicle called a Grillo PK-1000 Overlander. Only I think mine is smaller. But it's cute. Chassis, fuel tank, battery box, axles, drive shaft, wheels, and the seats are all off my M-274 Hunters Mule. Most everything else is off my 4010, I stretched the front sections to make it much taller, used the box off the 2 seater variant 4010, roll cage, steering wheel, wench and lights. I took my 4 cylinder diesel engine and put it in this. Then created my own exhaust from bits off a roll cage. Because of the M-274 parts, this is only open to FUD material.
