Ok am outside with my new toy right now. Yesterday I got a propane SMS from bass proshop. I was wanting the 24in camp chef but they are on backorder till the end of April. I have to say I like this smoker so far it has 4 racks and I can lay full racks of ribs in there it is bigger than what I thought it was going to be. I have it going right now I let it burn for about 30min on high and then sprayed some canola oil in it and it is still going.I hope I did not hurt it by doing that. How long should I let it go before I can put some meat in? Thanks for your time and info.
