I guess its something you have to live with as pictured above, the smoker box on top of the grates would never get hot enough to make smoke.
Mine is cast iron and it would take a whole tank of gas to get it hot enough if its located above the grates.
IMO, gas grills are for grilling, not BBQ'ing.
I would dispute your last statement. Barbecue is just low and slow indirect cooking, and that can be done on a decent gas grill just as easily as with charcoal. I've done a 7 hour smoke and BBQ on a pork butt with excellent results. It takes a bit more care than a smoker, but it's a perfectly viable way to achieve the end result. Not everyone can afford a cool smoker, or a BGE, or multiple cookers to cover all the bases.
I'd rather have a versatile gas grill than a one dimensional smoker. For me, that's what works best in both an economical and a culinary sense.
As far as using a chip box, I've tried several and I'm still convinced that the best one is a foil pouch with a few holes poked in the top.
