12 volt outlet

Have 20 hideout 26lhswe want/need 12 volt outlet. What kind job is this can I do myself Also how big inverter do I need for tv and sat receiver

Where are the 12 V receptacles going?

There are quite a few variables in play. First, you need to calculate the wattage of your satellite receiver (you didn’t give any info on it). Then you have to calculate the wattage of you television (you also didn’t give any info on that). Once you determine your wattage needs, you need to add some surge capacity for initial start-up and that will dictate the size of the inverter you need. Now using that information, you can size the wire and outlet appropriately for the current draw between your power source and the outlet. Now let’s talk about power; what size/type of battery and how many are there? This will guide you on power capacity available from the battery/batteries. The Amp Hour rating of the battery along with the amp draw (load) of EVERYTHING running off 12v in the camper or will at some point need 12v power (tv, sat receiver, lights, water pump, slideout, power awning, refrigerator controls, thermostat, water heater controls, smoke detector, CO detector, gas detector, radio, etc.) will determine how long you can power everything before recharging. Batteries should never be discharged fully, or even below 50% capacity. Do you have a generator? Do you have a plan B if the battery is drawn down too far? I am not trying to be doom and gloom, but it is all a bit more complicated that what size inverter do I need.

Lots of good questions I have dish Wally with playmaker antenna got two 12 volts with 140 amphour @ 23 A the specs say Wally uses 40 watts and tv100. What to put outlet on wall of entertainment center I’m new to all this trying to learn fro the pros

See if I understand what your wanting to do.
Run 12vdc from the batteries to the entertainment center to power an inverter that will provide 110vac for your TV and Wally?
This is a very simple and easy mod. I don't use the Wally but the work on our Cougar was basically the same.
You can run #10 or #8 (bigger is better) wire from the battery distribution to the entertainment center. Terminate the wire directly to a 350 watt inverter. Plug your TV and Wally into the inverter. That's it!!
Just make sure the inverter you choose has lug type terminals for connecting the wiring from the batteries.
What are you planning to use for keeping your batteries charged??

That's good advice above. Be sure to use heavy guage wire, as advised, and run a dedicated circuit with an appropriately sized fuse.

The above advice is good. I would just add that you need to add an appropriately sized fused at the 12v source. So if you're connecting directly to the battery then install a fuse at the battery connection. That will protect the entire length of the wire in case it should short out.
