Just read this whole thread, and since stories are being told, I'll tell mine. It involves coffee, Land Cruisers and an Expedition!
About 5 years ago, we were planning a big family trip in my 80 series. 3 weeks in and out of the back country of Southern Utah. About a week into the trip, we are camped out on the White Rim in Canyonlands. I get out the hot water, the coffee and the Lexan french press (from REI). After steeping, I go and sit on the tailgate and apply the presure that will strain the grounds out of the coffee. The handle refuses to press down. I press down harder, no dice. At this point I lean into it, full pre-coffee anger power. The coffee explodes out of the top of the press-all over me, and all over the headliner. From then on, the kids called that press the "volcano". The 80 smelled like coffee the rest of the trip.
At that point I switched to the little Melita cone filters, which I noticed Life_in_4_Lo adopted after our first trip together. That is the simple, low tech, 100% effective solution. For the record, I pack out my grounds and think everyone should too.
