I don’t have my truck while away for a while, but have read different stories regarding above question.

If not, I need to install a 12v outlet to power my camping refrigerator while driving. Seems ridiculous!

7.2kW onboard generator bed 110v outlets, specifically.

 

Yes the outlets work while driving.

 

Your trailer wiring 7 pin plug should be sending a 12volt supply to the trailer, but perhaps only with ignition on.

 

It does but I don't think it's enough to run the refrigerator.

 

Yes, Skip to 27:50 to see when they do it.

 

To clarify - I want to travel with a camping trailer in the bed of the pickup. Just got the fridge, so I’ll try it when I get home.

Power to my trailer via the 7 pin is another saga Ive written about - no clear answer to the “trailer not charging” message when I tow. All I know that works for me is to plug the trailer in after the vehicle is running. Stop for food or gas? Start truck, then go back and disconnect/reconnect 7-pin. That story is on a separate thread.

 

Yep, as the video shows they are charging the EV on the trailer as they are driving down the road. So yes the outlets can be turned on (generator mode) while driving.
