Kuerig

We use the single serve like hotels use, no water tank. We usually set it outside on the Lagun table inside the tent.

  I'm still looking for that ONE tree that has the outlet.....so, I leave mine at home & use ol' "trusty blue", the percolator I've had for 35 years! A little Irish Cream & the day is lookin' better already!
Seriously though, I saw LOTS of the single serves on sale at Target, KMart & ShopKo over the Holidays. You might want to check out the clearance sales. 
Note: If I know @Dalehelman is gonna be in the near vicinity, I pack some K Cups & sneak over & use his!

We use the Keurig K15 (mini) and it sits on top of our covered sink. It Is just the right size and marks just the right for our 2016 T@B Max S.

no paper filter, works well, fits my minimalist mantra. this is what I use wehn not in possession of Starbucks instant

French press or Turkish coffee for me. 

We've never had a better single-serve than from our Aeropress. Simple to use, easy rinse cleaning, and no plastic k-kup waste!
 

@Ratkity, Ok, I want you to put yer beverage DOWN! The first pot of coffee that my kind sweet wife Liz made for me was WAY beyond crunchy. I was busy doing some other things in camp, & Liz asked if I wanted coffee. I had ol' blue right from the start, (an old percolator style pot), and her thought was "he likes his coffee, so I'll fill the basket with coffee, and fill the pot with water, so he can have as many cups as he likes". Filling the pot with water, no problem...however, fill the basket to the top (Liz didn't drink coffee),.....not so much. Following filling my cup with coffee (and just a..tad of Irish Cream), we set out to go fishing. Having a lid on my cup, I didn't notice all the "floaties" until about the third good gulp. I spit more coffee grounds out than I can tell you from that one cup! Noticing me spitting a LOT, my sweet lady says "How's your coffee, and why are you spitting so much?" Reply: "Sweetie the coffee is great, but I think I swallowed a bug on the way down here". I sure miss that lady!

@tbaz, that's mine too! I also picked up an inexpensive single serve Chefman. It isn't fancy but it works when I am on shore power. I keep the MyJo for boondocking.

@ericnliz my step-mom, Rebecca, called it Under the Bridge Coffee, and she added an egg shell to keep the grounds towards the bottom. Guess we're all spoiled, aren't we?! 

@ScottG, Ummmm...it was more like chewin' tobacco than grounds! If I smiled real big, you coulda' seen the grounds! I had to face the other way to spit so she wouldn't catch on. When I say she filled the basket ALL the way up, I mean ALL the way up. (I usually fill it 1/2 to 3/4 full of grounds at the MOST!) I took the top off when we got back to camp, & there were grounds stuck to the under side of the lid, , the OUTSIDE of the pot & the basket lid was CLEAR off the basket from the grounds pushin' it up. Kinda makes me smile when I think about it now.  Thinkin' about it now...she never did offer to make coffee again. HMMMM.
@Homebodyatheart, A lil splash of cold water on top gives 'ya the same results with makin' the grounds fall. A lil something my Gramps taught me in huntin' camp when I was about 6, or 7. I usually don't even think about cookin' eggs before the second cup anyway!
@Twojgrams, Yep, mine's one of those blue enamel pots. Still have it, still use it & it's NOT goin' anywhere any time soon!

We also use a drip cone. We have a silicone model that is Melita #2 size and collapses flat, which is nice for saving space. 

I didn't how simple my life is since I don't cook or eat veggies. All I have is either perked coffee in my trusty stainless pot (done correctly - a slow timed perk) or VIA if I'm feeling a desperate need to wake up quickly (sometimes both!). If I have an electric campsite, it's the simple Keurig.

I can bring it outside with my small water container and offer cups of coffee, tea or hot choc to my peeps although some of the earlier risers usually beat me to it! So I sleepily saunder over with my first cuppa and park myself 'round the circle and contemplate fishin', just visitin' and catching up with all or just go to the local diner and have 2nd breakfast. A nice lazy Saturday always seem to include the last two and fishin' is replaced with dem fish stories.

@ScottG, yup, that’s what we do.  I have an 8 cup stainless steel percolator I picked up from Cabella’s years ago.

@ericnliz- usually we would say we want pictures... not so sure on this one!
