Because it's somewhere between a truck and a tractor and costs more than buying a dually, 5th wheel flatbed, and a tractor.
It's also slow as shit, we tow at 70-85mph in 'Murica. Sometimes faster, I was hanging behind a oversize flagged batwing shredder at 90mph this morning on a rural 2 lane highway.
We can also buy picrels for the same price you can get a Peugeot 206, but very few do it because it suffers from same problems unimog does,.
