After looking at it, it is very similar to my current setup. Char-griller 5072 dual purpose. I like mine, it just has to be babysat when smoking on it. But, other than that, I have turned some good meats on it.
In the end though, dedicated tools work the best.
Would you use an adjustable wrench as a hammer just because it has flat surface for striking? Of course you would. But, would it work as well as a 32 oz Estwing framibg hammer? No.
