12v output

i recently bought a forest river flagstaff 205 pop up and was wondering if there is any place inside the camper that has 12v output (terminals or "cigarette lighter" type plug in) where i can connect an inverter. if not where is the best place to connect an inverter. i mainly want to use the inverter for a single use Keurig coffee maker.

Be careful with an inverter. Depending on the size it will deplete your battery(s) very fast. Do a little research. A coffee maker will draw lots of battery amperage.

What size inverter did you plan on running the Keurig from? The Keurig website says it draws 1500 watts during startup. You are looking at needing about 125 amps 12V DC. You are not going to get that out of a cigarette lighter type plug.

The Keurig website says max 400 watts after initial heating, so that is still 33 amps.

I highly recommend a percolator on a propane stove for making coffee without shore power. And it's actually just pretty darn fun to make old school coffee!

Even a tiny 300 watt inverter is going to draw over 20 amps of 12.7v DC running at its full capacity. That requires 12 gauge wiring at a minimum and it still wouldn't be enough to even power the warmer on an electric coffee maker, much less the brew function. That would require a 2000 watt inverter and would require cables from the battery bank to the inverter of "welder size" ie; "0" gauge possibly. You aren't going to get that out of a couple 12 volt batteries.

To power a keurig, you will likely need a 1500 to 2000 watt inverter. Hopefully, you have at least 2 golf cart batteries to handle the 150A, this coffee maker will pull from your batteries.

You would be better off running a generator or find a stove top method of making coffee. We use a Mocha cup style maker.

You still need a way to heat the water, though.

And I guess if you did only want a single cup, making coffee in a perculator would be a bit of a waste.

We use one of these to make a few shots of espresso along with a tea pot to make boiling water to make americanos.

The OP did say a Keurig, which are single cup coffee makers.
If you want a pot of coffee and don't have electricity, get one of these:

I've had mine for 15 years.
Electricity to make coffee isn't necessary if you have a gas stove.

Even if it does exist, you've been advised an inverter that plugs into a cigarette lighter type plug (and it's associated light gauge wiring) WILL NOT run a Keurig. It wouldn't matter if there were six of them. The result is still no.

It's relatively easy to add a 12V receptacle inside the trailer anywhere there's a 12V switch, but they would only be good for 10-15 Amps max. I'm going to add a couple for easy overnight cell phone charging near the beds and just relocate the CAR charging cords to the trailer while dry camping. I'm not seeing any other use for them.

Don't forget that when adding something like a 12 v receptacle to an existing circuit any load plugged into it is in addition to any other load already on the circuit.

Just hooking up at a switch might lead to blown fuses when everything is on ans well as the added load. Unfortunately RV's don't have many individual circuits.
