Good evening. I just purchased my 4d yesterday. I have been watching and reading for the past 2 Yeats. I debated on the 3.5d and I just decided to work some OT. I got my pennies saved up and made my purchase. I cut my teeth on offset smokers in Texas. I even went as far as to teach myself how to weld and started making smokers for friends. I am really excited about the 4d. I hope to be able to do lots of deer JerKY, bacon and sausage. Thanks for reading, Ray from Pekin indiana. Just north of Louisville KY.
