We have a #4 Melitta funnel. The funnel, a ziplock bag of filters for a couple of weeks worth of coffee, an Insulated carafe and a small container of coffee good for 5 or 6 pots all fit in a plastic carry box we picked up somewhere. Works great for us, if it is cool/cold I make it inside the camper first thing in the morning and the heating of kettle of water takes the chill of the camper. If it is hot I make it outside on a camp stove. Also works when we visit my Mother who doesn't drink coffee, we just pack it in the trunk when we visit. As a bonus we bought an electric coffee maker for home that takes same filter so we always have a supply on hand.
