New Owner - Used Model 20

I didn't know what the model 20 is, so I searched on the website and found a thread that claims the 20 is the same as a 25 except for having painted steel exterior and no food probe.  So I assume the accesories would be the same.

I have a 20 and as stated above, it has no meat probe and is painted meatal sides, other than that all the accessories are the same.

Thanks for the answers and sorry for the late reply!  

So, more on this smoker.  When I got it there was a thick coat of black, greasy soot on the inside.  The fellow I bought it from said he tried to clean it and gave up.  I found that Purple Power degreaser just melted this stuff!  I was careful to keep it off the heating element, and used rags and 3M scrubby pad sponges, and a toothbrush, and after a couple of hours it was as clean as new.   Well, not really, but very good!  I rinsed with a spray bottle of water and more clean rags, kept doing it until I thought I had most of it off.   I then ran the smoker, empty, for a few hours to burn off any residual chemicals. 

I learned that these are designed for wood chunks, not the chips I had for my gas smoker.  I found chunks at Lowes, maybe not as good as Cookshack's product, but will do for now.  I got Mesquite and Hickory.

Haven't done a smoke with chunks yet,

Would really like to get a couple of new stainless racks, the rib rack, and the cabinet stand, but will have to save up for those.

Good luck with it! Do a break -in smoke with a pork butt just to season it as if it were a new smoker. You'll be glad you did.
