Sorry, can't help you on that model, but it looks like there are a few reviews in the smoker section for something similar (outdoor leisure products..smoke hollow), and for some reason it won't let me paste the link here. Go to the "smokers & more tab, scroll down to horizontal offset, and look for the model there.
I got the Oklahoma Joes 3:1 a few months back and like it so far. I had to do some minor mods to get the smoker to be more controllable with heat and smoke. The propane side is incredibly hot and does well with everything cooked on it so far. I haven't cooked over charcoal yet, just smoked. There is plenty of grill and smoke space for a small family. If you are looking to do large amounts of meat, it may not be able to.
