Hi guys, I'm hoping someone can help me out identifying my new purchase. I just picked up a very slightly used Masterbuilt digital smoker from a Craigslist post. As in the title model number I am trying to find out if this is a 30" or 40" smoker. It does have 4 racks and was sold through the NWTF National Wild Turkey Federation. Also the MFG Date is GH04721. Was this made in 2011? I hope someone on this forum can tell me about this smoker. BTW This is my second smoker, I've had a Big Chief Smokehouse cold smoker for about 2 years now and have really enjoyed it.
