@SmokeZilla - your consumption calculation... is the calculation done in red solo cups?My consumption calculation was spot on for the 8 hour cook I was performing. If you fill the hopper for a low and slow I would be willing to bet you get the RT advertised 40 hours with the Costco pellets (YMMV).
You like to keep your hopper empty-ish? Why? Swapping flavors? Pellet Humidity?
