Will 12 volt socket with inverter, power tv and receiver?

I have a Grey Wolf 21rr and above the tv is a 12 volt socket. Can I plug in a small inverter and operate my tv and a satellite receiver when when no electric hookups are available? Is the wiring in the trailer adequate to do this?

What kind of TV?
Average consumption of a good quality 26" LCD is between 40-60 watts.
Satellite receivers about 20-40 watts.

The lower quality of the components the more wattage they will consume because of low quality power supplies.

The tv that came with it is a 19" and says 40 watts on the back. I plan to buy a dish and receiver between now and spring to be ready for next years camping season. Also I would like to install a little larger tv. I would like to be able to spend three days boondocking or dry camping with two deep cycle batteries and no generator.

Not sure you will get three days without a charge. Maybe a solar panel to refresh your batteries during the day.
I would also keep your inverter under 180 watts.

The Winegard Wall Plate 12V socket is rated for a maximum of 7.5A so that's about 90W.

Check your battery AmpHour capacity - typical values vary from 50Ah to 120Ah for a single 12V Deep Cycle Marine/RV battery so you cannot run too much equipment before you deplete it.

If that socket is only rated for 7.5 amps then I would be thinking to either run a new power cable for the inverter or go all 12v TV and Satellite receiver.

Wouldn't that socket be fused for protection from an accidental overload?

If you are planning on a new tv think about LED vs LCD. LED can be bigger while using fewer watts.

It should be fused, unlikely that it isn't.

Fuses don't provide overload protection, they are for faults.

The smallest fuse in my breaker panel is 15A and none of the labels mention the 12V outlet, which doesn't seem to have an integral fuse.
