Found this site by accident looking for ways to fix issues on my dads smoker. Found a lot of good info while looking the site over and decided to stay and join. My smoker is a duo Char griller 50/50 with a side mounted fire box. The smoker I have taken and started using from my dad (since its been in a box since the day he got it over a year ago) is a digital Bradley 4 rack. love using both smokers.
