It's practically a given in the T2K universe that at some point the PCs are going to be fueling their vehicles through the production of an alcohol still. My question is -- how realistically practical is this? Can you really run, say, even a HMMWV effectively on moonshine? What about something heavier, such as an M113...or (more importantly from the point of view of my PCs) the M4E8 Sherman that had been sitting as a monument in a city park for a half-century and had been recently refurbished.
