trek 4wd safaris
Observer
I could cut the handles off, weld some 'feet' to the bottom that will clip into the KK's base. I'm liking this option if nothing more as a proof of concept before making my own. Its $20, cast iron and close to the right size. Edit: I'm wondering if the 9x20 is the actual cooking surface size. Add the grease trap and sides and it could be more like 11x21 which is just outside my bounds.
i cook for up to 20 people on the three burner versions of these, they are HEAVY, but distribute heat well.
