Aeropress works well if weight and space is a concern and you are a coffee elitist Some people swear by them as the best way to make coffee, period. It's kind of a pain to me to try to make it in the morning when my brain is not working, so I don't use it much. Check youtube for some videos of it.
car camping- I have a thermos brand insulated french press that I like.
really lighweight/ low hassle is the Starbucks via instant coffee. It is really good, good enough to serve to coffee lovers, and is about .50 per cup when bought on sale at costco. The tasters choice 100% columbian that walmart sells isn't terrible, but it's not what I would call good coffee either. But if you're going to add cream and sugar anyway, you might get by with it. It is about half the cost of the vias. My afternoon ritual is to heat 16 ounces of water, mix in two of the aforementioned tasters choice packs, and a pack of hot cocoa mix. It makes a decent mocha.
