So I have the dryer vent mod on my Chargriller, but I constantly fight with the loss of grill grate space in that area. What I'm wondering is, what would happen if I cut a hole in the side of the lower half of the smoke chamber, lefthand side, just below the grill grates. Then plumb a new stack out and up. Cap off the existing exhaust, and call it a day. Would that make it too low? Since the dryer vent is already grate level, and I can't imagine another couple of inches making that much of a difference.
