Upgrade is best - I found that out!I had a smaller version of the GOSM smoker last year for a couple of months. I saw early on that it was way to small for my needs, so I ordered the "big block" version on-line.
I wish I would have seen the posts about keeping the original equipment because now I feel that I could use the smaller one also. I gave it to a close friend that seems to always be giving me his "hand-me-downs" (grill accessories, etc.) and I thought it would be a good time to return the favor. He and his wife tell me frequently how much they like that small smoker so it is still being put to good use. If you can hang on to your original equipment I am sure that you will find a good use for it as well, however an upgrade is the way to go, just as the other posts recommend.
