Does anyone have the height, width and length of the frame the kettle sits in. I ask this as I am going to pick up a cheap performer that I don't know whether it is an older one or newer one do know it has gas assist. It is an asking price I cannot pass up. The seller has it in a storage unit and I am meeting them tonight. They do not know or have pictures of it to tell me which one it is. I am taking the girlfriends car as it gets better fuel mileage. Any Help is appreciated.
