Hi all,

I have an 18 lb. bone-in roast I'd like to smoke for Christmas Eve dinner. I have a marinade ready to go and will let is soak for 24 hours.

The question is, how much time should I expect for this roast to cook in the smoker? (Medium rare)

I have probes to get an exact temp, but I'm looking for a ballpark number to work with here.

Any help would be appreciated!
