You did not state what model of camper you have so the answers are going to be generic.

Only if you do not have the option to run on propane AND you will not be stopped for more than 30 minutes at a time.

Running on an inverter when the vehicle not running will drain the batteries pretty quickly.

From a practical stand point and unless you have a lot more battery power then you have originally, the answer would be no.

It will be running off the truck while travelling.

Still not a good idea as the amp input from the TV is likely not going to keep the battery in the TT charged. The fridge s/b precooled prior to beginning the trip. You can then run on propane or leave it off [your choice] but running on propane is my choice. Not sure why you would want to try to use an inverter? Propane is realitifly cheap and readily available if you run low.

Been there, done that!


Doesn't work nearly as well as one would expect.


Run on propane while underway or shutdown the cooling unit and move ice packs.

The output from the TV alone will not provide enough energy for the fridge and keep your battery charged. The only reason I can keep the fridge running on the inverter while traveling is because the TT's SOLAR panel is pumping out around 19 Amps which handles the bulk of the loads.

I have the additional 12V "accessory" lead wired on my 6 prong connector that could be used for this. I also removed the stock alternator and replaced it with a "high output" 220 amps unit: it does not continually charge at a rate of 220 amps, but will maintain the battery. At full load conditions during idle, it peaks at 110 amps, and at 1200 RPM, peaks at 220 amps. Something to consider over using propane if the OP insists.

Ford uses that center pin as a trailer "BACK-UP light" lead. It only is activated when the truck is in REVERSE". I have a 2012 F150 (260 or 280Amp Alt) and have verified this. Check yours out.

You would need to rewire it so that it will provide 12VDC when the engine is running. Best to run a new wire (fused) from the front fuse panel to the connector.

What is the reason for not wanting to run on propane? Cheap, easy, safe and works well.
