I have two backwoods, one party and one extended party. You can run them low, you can run them hot. If you are cooking at 245 or lower, use the water pan and it's awesome. I personally have found if you run higher temps 245-285, go buy some fire bricks from Menards, cut them the size of the inside of the water pan, and cover it with aluminum foil (easy clean-up). This helps hold a more steady temp and uses less charcoal. I also built this for my Backwoods to control how much charcoal catches on fire and how fast. It's not perfect with higher temps because the embers jump across, but still does allow me 10 hours on a cook.
Also, when doing some comps, this just CAREFULLY goes in the back of our Ford Escape with just me and a sheet of 2' x 4' piece of plywood. Place towel over the bumper, lean it back, pick up the bottom of the plywood and smoker, and slide in.
