Hello, I just purchased the Dyna-Glo wide body vertical smoker on Amazon and it will be at my house in 2 days. Im by far not new to smoking meat. I mainly have been using my 2 UDS. I've seen people talking about mods for theirs. I'm wondering if I will be able to use it without mods right away. And can I mod it later and seal it? Wanting to try a rack of ribs this weekend to test it out. Also is it possible to use just wood in this? Or do I have to use charcoal too? Thank you in advance.
