Just got my Lang 36 stretch....have cooked on it a few times. Love it,,,Que has come out fantastic so far. Still getting used to it. have some big temp fluctuations from one end to the other so that will take some time to figure out. The leaks out the skip welds? Big deal....not anything at all to be concerned with....it's BBQ, not the space shuttle. I see no need for silicone, nor foil at the door. The temp lost is extremely minimal.
My digital thermometer held at 234 for 4 hours. Added a stick every 35-40 minutes.....usually when I started seeing the temp hit 229....that was a cue to add...and it took 5 minutes to get back up to 237 and then even out at 234.....that's good control......
Now .....that was at the center where my probes/meat were located. At the unit thermometer at the end of the lang, it held at 175 almost the entire cook....didn't check the hot side, but thats were I cooked Dutch's baked beans and the potato's.
I noted Chipolte Q noted a leak around the drain flange. I hope folks understands that is by design. the square tube drain is for grease from ON TOP of the plate, but as the tube travels thru the bottom of the smoker, there is a small gap. This is so when cleaning with water, any overspill of water that collects in the bottom of the smoke chamber can drain out the bottom. It follows the outside of the drain tube and is creosote/water mix from the smoke chamber. All by design....if water were allowed to sit in there, it would end up rusting out the bottom of the cooker in short order.
All in all for what I paid and what I got, I'm a happy customer. A couple things I could nitpick about, but I won't Won't be looking to upgrade anytime soon as the stretch should take care of all I'll ever need. Shipping was quick when it shipped. From GA to WI took them 1 day. Now they were backed up with orders and mine took 9 weeks, but I changed my order once and put it on hold once too. My fault.
