I don't use WVO, but I've spent time living on a two-tank WVO bus.

I don't have much to add from what you've heard.. I'd generally recommend a heated system instead of just blending in one tank, but you can get away with blends on these mercedes. However, two tank systems, or at least a heated one tank, are how you do it right.

Dana's plans are good, he's a good guy and well respected.

peace,
sam
