When one vehicle fails, always make sure you have a suitable backup. This time on Roadkill, Freiburger and Finnegan attempt to road-trip the Hemi Gremmie only to be foiled by engine trouble. Instead of roadkilling fully and risking more damage, they do the only sensible thing...continue the road trip by "street legalizing" an Off-Road Race Truck and driving it 400+ miles on the highway.
