Cooked Turkey, cooler, 40 minute drive = no problem
I use to use foiled bricks that I heat in the oven to 250. I have since picked up a couple 2 1/2" thick hunks of aluminum that just fit the bottom of my cooler.
I wrap the bird with foil and put on a rack and in a pan. I put bath towels around to take up space.
Everything works out great. Have done tri tips, turkeys, chickens etc this way.
I found the aluminum at a local recycling yard.
