I purchased the 24DLX on 9/22. During assembly. I discovered the smoker had been previously assembled. At start up the display read sensor. To shorten the story I will say I returned the first smoker to Sportsman's with no issue. My second Camp Chef smoker has a temperature swing of 100 degrees. 1st time talking with Camp Chef they sent there brand pellets and suggested lowing the chimney hat. No difference in temp. swing. Camp Chef has now sent a new temp probe for me to install. No change in temp swing. Camp Chef is now sending a hopper for me to install. Two different camp Chef smokers with issues. Frustrated I am working on a brand new smoker!
