I LIKE multiple carb setups!
And given your location, I would prefer a single original W-1 over the YF. The reason is your location. The W-1 has a mechanical power system while the YF has a vacuum power system. On a truck doing towing in the mountains, the mechanical system is superior (opinion).

Good point on the hills, Jon. I'm strictly a flatlander around here.
I will get back to you on dragging the stump at 70 MPH.
