The fewer and smaller your RV kitchen appliances the better. We are replacing our countertop pod coffee maker with this simply elegant device. Just slowly pour almost boiling water over the ground coffee while basket and filter sits on your coffee mug. I tried it with 20 ounces of water and 2TBSP of medium grind coffee. A perfect cup and cleanup is much easier than a typical coffee maker. It stores in the cabinet with our 2 mugs instead of taking up counter space. I bought this one at Publix but they are available lots of places.
