I still have my stainless steel "stove-top" percolator pot from my field days as a jarhead... add H2O, grounds and fire, and yuh gots coffee...
We have a burner on our gas grill, and a campstove percolator, but even better, we have a couple of inverters and some GOOD batteries. So we can have coffee from our Zo thermal coffee maker. Yum.
Y'all stay safe!
