ok so I have narrowed my search for a propane smoker to these two. they seem comparable in how they are built. My research on here seems to indicate that the Smoke Hollow has a harder time with running cooler. maybe a lack of vents. dunno.. For those of you that own these smokers, which one's are easier to keep cool, or are easier to modify to run cool? do the GOSM have vents at the bottom? I want to be able to run at 160 for certain types of sausage I like to make, but still want to run the hotter temps for big meats. I am looking at the bigger box versions. 34 to 38 high and 24 wide.
