No. No need to refill wood on any smoke with these smokers.
I always use a aluminum loaf pan for my smokes. Liquid varies based on what I’m smoking. For ribs, usually apple juice or orange juice. But yes, 225 temp and unwrapped and at 4.5 probably I’ll open up and test by feel. If they need more I’ll close door and check in 30 minutes. Once they are where I want them, I’ll wrap in foil and let them sit for a bit in a cooler wrapped in a towel while I get my sides ready. Sauce them if you are using sauce when served, especially when feeding friends, as some don’t like sauce and others do.
Either a pork rub isnused or, if I want the meat to really stand out, I only go with salt and pepper.
