The best explanation for the continued existence of Huddle House that I've seen. Actually, I haven't seen HH in years, and was hoping they'd died out. Alas.

Yep, same engine, drivetrain and fuel system layout. Well, except for the ones with 4WD in first gear (Schwimmwagen, for example), which ran a driveshaft from the transmission nosecone up to a transfer box on the front wheels behind the front beam, sitting underneath the gas tank.
