Finally got the opportunity to get smoker I have wanted for a few years. Trashed the fridge today and found a used vault a few hours away online about 2 hours later. I am driving to pick it up Tues. It is the original version with the sliding damper but I already have a machine shop building a plate to screw on to convert to 1 1/2" ball valve. The vault has Stainless side shelf and comes with BBQ guru Digi q. Now I have 3 so I need to buy another smoker. Cant wait to get this bad boy home. Test fire will be next tues to get a good feel for it then the Brisket is going on all day WED. Will post pics when I get it.
