Having the XL since Xmas, I have found the problems that everyone else has. I sealed the door with wood stove gasket from Lowes, added a bent plate to the door to keep the drippings from dripping out the bottom all over the deck, added a 4" steamer tray (hotel pan) for a water pan/drip tray and replaced the chip pan with a cast iron frying pan sitting on a gas range burner grate. The other thing that was bothering me was the height that the unit was sitting. I built a stand with side tables to make it more accessable, more mobile and more usable. The other thing is I connected it to our buried propane tank for the house, so I didnt have to worry about running out of gas during a smoke.
I have done several sets of ribs, chuckies, butts and a few chickens and all came out good.
Over all I think it is a good smoker for the money.
