12V DC outlets?

How many do people have? There was only one in my Bigfoot 17. Since I am redoing almost all the electrical, along with the furniture, I can put in more than one easily. I'm thinking that car-charge adapters for many gadgets might be available, reducing or eliminating the need for inverter/generator/plug-in much of the time.

I would think at least five 110 and a minimum of two 12 volt. An outside one of each maybe helpful as well. So many devices are 12 volt (with an adapter) and if boondocking it would be nice to run your notebook, TV, charge cell phone and use CPAP.

If you ever go into a Flyin J or Pilot truck stop they will have one whole section with 12 volt stuff to plug into 12 volt power outlets, almost anything that you can think of. I would think one in the kitchen, one in any sleeping area, anywhere and everywhere. If you go to the J or Pilot you will see what I mean.

Good idea. I often go to Flying J on road trips, but never had cause to check out the adapters. Ultimately, I'm not sure I'll need to plug that much stuff into AC if I can get the right cords/plugs. Most of the electronics I will use are battery powered DC, so it seems silly to convert the power twice to charge them.

I mounted one on the front, 1 on the rear and one on each side close to the wheel. To use one of those 12V powered jacks and/or air compressor. B sure to do a water tight one for outside locations.

I added an extra 12 VDC outlet under the table inside and on the curbside outside. I used Marine Grade Cigarette Lighter Socket for both. I also have another one with battery clips to use on the travelside. Another 120 VAC was added up front inside.

I have one inside and one outside. I have only used the inside one to charge my cell phone.

I have three. Two I added, both marine grade. There's one at the back for the television, one in the footwell of the side dinette for recharging stuff and one outside.

I have 3 d/c outlets.

One on the left side kitchen cabinet that I had installed by the factory when the trailer was made.

Then the second one is on the other end of the cabinet that I added shortly after getting my trailer.

The third I added recently to the outside, curbside next to the factory installed a/c outlet. I use this one for my water pump to pump water from a water container into the holding tank. I've also used it for charging my phone.

What kind of water pump are you using, Joy?

I had the joy (?) of pouring about 20 gallons of water from 5Gal blue jugs into the tank this weekend, and it's no fun!

I had no 12V outlets, but added 2 this fall. One is a single outlet by the side dinette, and the other is a triple DC outlet near a shelf I installed for a CPAP so I can also plug in a phone charger if needed.

We have three: one in our 5er loft, and one on either side of the dinette, mounted on the lower kitchen cabinets and facing toward the dinette bench. The dinette pair come in handy for plugging in phone chargers and the like. Only rarely ever use the one up in the loft.

I always steal as many ideas from your work as I can. So, before I steal another one, are these on a separate, fused circuit? If so, what size wire did you run?
