Did they say it is a gen#1 like you had.?
How do you have the manual for a smoker that isn't on the site and can't be found? Did you get a PDF from somewhere (where?) or is it a hard copy? Care to tell us what the features are of it? How about maybe a photo of the smoker image if it's on the manual?
This is scary that no one knows about this model. I am starting to wonder if I made the right decision to let them replace my smoker with this model. Its weird that this has been available for sale sine Dec 2014 and no information is out there for this model. I can not even find a price on it. The unit is a 30 in with window and looks like the gen 2 with digital controls on front it has a new drip tray that goes under the front base instead on the outside back and has the vent on the top left.
Unless I am seeing it wrong that is not the same smoker in those pics. One has a top vent the other a side vent. So I can't say for sure what it is.
