Never too late join the party. I went from an offset stick burner (Brinkman) and really enjoyed it. But getting old and lazy, I did tire of feeding it. But it was worth the effort. Food was great. Going electric with the Amerique was a simple transition and the food nice and smokey (too smokey ONCE) and I did not miss the tasteless smoking which seems to be very important for some folks.
After 3 or 4 hours you may notice the smoke has diminished/vanished. Not to worry. The meat has absorbed all it can. Ever wonder why a smoke ring is shallow? The particulates/smoke could not penetrate any further. Here is a link explaining the science of smoke. Enjoy your smoker.
