I'm looking to purchase a pull behind commercial type cooker. Something along the lines of a Southern Steamers Alumigrill I. I'm not even sure that outfit is still in business as I have called and left messages to no avail. It doesn't have to be aluminum of course, but that would be nice. Anyone have any leads or reputable outfits that build these?
