You are allowing it to get too cold if it is fluctuating down to 205F, that is killing your cook. Personally, I would pull it and stuff it into the oven at 400F and get it done. Raise the pit temperature to 300F or more. You can wrap, I would add some apple juice or liquid, foil wrap, that will help.
Involving the Army in a simple picnic turns out to not be as simple as I thought.
