When is a brisket done?

There’s the key right there; let it rest like @mikeporter616 said. And, like @SmokeOCD suggested, keep the point on the hot side of the grill and the flat on the cooler side. It is important to really get to know our grills and their personalities.

Which side is hotter on your Trailblazer?

Which side is hotter on your Trailblazer?

My Trailblazer is slightly hotter on the left side but not much; 10-15 degrees. I attribute that to the slope of the drip pan and the fact that heat rises to the high side. Because the Trailblazer has a fairly small cooking chamber, I think heat gets distributed a little better than with larger grills. YMMV

What is the best way to let a brisket rest?
Keep it wrapped and set inside a cooler to keep warm? Or can you let it rest on the grill? I imagine it would get cold then? Especially in winter...

Either paper wrapped or foil boat in a cooler, or my preference is in my Breville counter top oven for 8-12 hours at 150 degrees wrapped in a foil boat, fat cap up, with added smoked waygu tallow underneath.
