smoking time...

I've never done this - but what I would try is to give yourself more time than you need. Figuring an hour per pound, if it's a three pound tri-tip, give yourself three hours.

Cook it with a temperature probe in it and when it comes up to your target of 135F, pull it and wrap it in foil. Then you can place it in the center of a cooler packed with crumpled up newspapers to hold until serving time.

That's what I'd try anyway. I'm sure there are others who have actual numbers for you around here somewhere.

If your target temp is 135, I would pull it at 125 foil and rest as it will continue to cook during the rest.

Depends upon the size of the tri-tip, but I would think a couple hrs would be plenty of time. Should also have time to let it rest properly, and be sure to slice it against the grain :hungry:
