The B-66 is a vehicle in Spintires and MudRunner.


The B-66 is a light 4x4 military style truck. It serves mainly as a utility vehicle, as it is not able to carry logs of any kind. It only had a few addons, and is best suited as a rescue/utility vehicle, or a scout vehicle. It is surprisingly capable, with an always locked differential, and all wheel drive.
