That kettle and rotisserie looks awesome, I looked it up on amazon.
Off topic a bit:
I'm still thinking of designing a bbq that will utilize the Son of Hibachi battery operated rotisserie. I used to have one of those portable CharBroil propane bbq's. I fantasize about marketing such a bbq on an infomercial.
Normally, the spit rod would be in the way as you partially closed down the hinged square lid, but there would be a cutout slit on each side of the top lid to allow closing the lid with the spit rod in place. I'd redesign it over what the CharBroil one looks like, but you get the idea. You wouldn't be able to fully close down the lid, but it would be closed down enough to keep the heat in.
I found a pic similar to the Charbroil bbq I used to own 15 years ago.
I was able to partially close the lid, but cutouts on each lid side would allow the lid to close more fully over the rotisserie rod.
I attached the Son of Hibachi rod holder ladders to the side handles. The ladders are made such that there are thumb screws to attach to the side handles. Man, it really cooked up game hens and chicken parts to restaurant quality. 1 D battery lasted me 2 cooking seasons! The battery rotisserie is geared down and has a surprising amount of torque.
BTW, since my CharBroil wasn't the same width as the Son of Hibachi (junk) I simply took the spit rod to a grinder and ground out the square rod to roundness to sit on the ladder to my desired width.
You could, of course, put steaks on the grill part.
So, do you think this idea might appeal to buyers of portable grills?
