They carry around 2 tonne.
You would be lucky to see 10mpg.
They are extremely slow but easily converted to diesel for similar performance and better mpg.
x254, G350, Duster, S320, Mach1, 900ss and a few more
Stop it... I was looking for a Gaz truck not long ago (to convert to an overland thing), until my other half (sensibly) convinced me to get a catC license first...
I Love these old Unimogs but it would be a toy rather than an overlander. To drive one as far as the Atlas mountains feels like a rtw epic. The diesels don't do much better on fuel and if you think digging a normal 4x4 out of axle deep sand in near 50 degrees c is fun try it with one of these!
