N8 man I like your 3 rack system you have. I have to agree my smokers went from simple to more additions after reading here from all the people that post lol.
Smokerking - Thanks for the advice on the racks. Didnt know they were countersunk. And yes I found out in a hurry about a level rack the hard way. In a hurry on my 1st drum and put 4 bolts to hold the grates HUGE MISTAKE.Then drilled the hole for the therm and put it literally right at grate level lol. All has been fixed. Just in a hurry to complete and start smoking but my other drums no issues as I took my time.
