Bruce you are correct, I cooked on the gas grill but never used the side burner until last week and here in the high desert of AZ as you have heard from Rich Dahl it always blows and it makes it hard to use that burner . I would much rather have a self there.Kevin: You can use a standard Silver B side table to replace the side burner. I have always thought the side burner would be nice, but I know from experience what most say about them and that is that they are useless with any kind of wind.
I know that Bruce has been pretty sick, so I hope you don't mind me jumping in. The short answer is, yes, because the frame is still not the right size. The burners and control panel are all different, so you will have to do some serious adjustments/welding like Bruce did to make it all fit. But, it CAN be done!
Alex, even if you don't put in a deep box in the platinum I'd still take it at that price (maybe try to offer a little lower)....it's still an excellent grill even with the stock firebox.
