No options as far as I know, I think you could customize something for a little more money. I think it would have to come out of the mold/cast like mine and then they would have to cut that portion out and build something by hand for you. Just depends on what you want to spend. I don't know if I'm going to run A/C either, we tend to stay away from hook ups and don't spend a lot of time in extreme heat.
