I've spent more money than I care to think about on trying to find the perfect coffee solution. We like strong coffee and getting it strong enough seems to be a problem.
1. percolater: takes too long, messy to cleanup
2. single cup funnel: can't get enough coffee in it to get the coffee strong enough
3. French press: my favourite coffee but too much mess
4. Coleman propane coffee maker: pretty decent but takes a lot of room in the truck camper.
We now carry a mini Keurig for when we have power and I just picked up a manual Keurig/press for when we don't. I haven't tried the manual Keurig but the review seems promising.
