Had my XL for a couple months now. Really like the size, but some of the workmanship seems a little shoddy. Do the doors on your units close evenly? It's like the door was cut a little too long on one side. It doesn't really affect performance (aside from contributing to the already well known crappy door seal), but it's just somewhat dissapointing after all the great reviews.
After 8 or so smokes, I've noticed that using an extra large foil tray works very well for increased water capacity, but it creates a cold zone right in the middle of the smoker. The heat goes around the edges of the foil tray, and continue up along the walls and apparently out the vent. To hit 225 in the middle of the smoker, I've got to give it enough gas to maintain 300, which is obviously a waste of gas. I'm considering some sort of baffle setup to get the heat back to the middle, but I haven't seen anyone else on here do it yet. Curious if the top mounted smoke stacks would draw the heat back in, or maybe if a vent was extended towards the middle somehow off of the existing vent. Ideas...
