Test results!
UDS' are funny beast. We ran 1 with Cowboy Lump and 1 with Royal Oak Briqquetes. With 5 lbs of Royal Oak we only got 2 hours of actual cooking temps (225*F), with 4 1/2" air vents open, Not enough to even cook a fattie!!! The Cowboy Lump we are working on 8.5 hrs and still hanging in there with 9lbs to start with. The only problem that we had with the lump was the temp shot up to 250*F and we could not get it back down, Even with all the air vlvs shut it would not come down. Up untill an hour ago we only had 1 vent partially open, it was odd because right next to the this one was the Royal Oak with all the vents open. I dont know if Im a frim believer in this whole UDS thing, it may be like the moon landing, staged by the Government. More to come!
