So, the first smoking turned out not so good.
The bacon when I cooked it had a really bitter creosote type flavor. Like I was eating a campfire.
So I posted some questions on the smoking forums and got a lot of great advice. Turns out those tube smokers produce way too much smoke to be used in my RecTec when it's not running (because there is no air flow unless it's actually powered on and the fans are in use pulling in air). So I had bad air flow which meant bad combustion, so I overpowered with bad smoke and probably also had a condensation issue.
I just finished my 2nd attempt yesterday, and it turned out awesome.
I only filled the tube smoker up halfway and then evened it out into a half-moon cyldiner of pellets, to more closely resemble the tray/snake smokers that don't put off as much smoke. I also cracked open the lid of the RecTec about 1/2 inch and set up a Lasko tower fan blowing directly at that opening to encourage better air flow.
This time it worked great and I didn't get any of the bad smoke flavor.
Forgot to take photos along the way, but here is the cold-smoked pepperd bacon sliced and a couple bacon sandwiches from it. I also did a maple brown suger rubbed one that turned out great also.
