There’s a lot of confusion right now about diesel engines, DEF, and what the EPA actually changed—and in this episode, we’re cutting through the noise.

Plus, oil prices are climbing again, Buc-ee’s continues its rapid expansion, and there are some interesting developments across the RV industry—including a possible return of Winnebago fifth wheels, and a behind-the-scenes technology that could change how RVs are designed.
