Best way to add standard AC sockets to the truck bed?

I need to add a couple standard 120-volt AC power sockets to the truck bed. Mostly for a charging station for astrophotography and camera gear, satellite phone, etc.

Requirements:

• built-in look with all wiring hidden behind panels
• sockets that are protected from the elements
• be able to run it with the truck turned off

So I'm not keen to just buy an inverter and mount it on the wall of the bed.

The Tacomas have power in there already. Eminently annoying the Tundras do not.

What's the best way to do this?

I should add that my bed is covered by both a spray-on LineX and a BedRug.

 

Take apart a pure sine wave inverter, extend the receptacle from the cab into the bed, and use a weatherproof style socket. Use a switch, connected directly to the battery, to trigger a relay, also connected to the battery, that provides power to the inverter. Also, put a fuse on the switch and relay.

 

before you do this, have you considered, or what's the dealbreaker for using a portable power station, like a Jackery?

It isn’t a show stopper. But when I get to where I’m going, I need my Jackery at full power and my other batteries and devices. I’d prefer on-board truck-mounted sockets to charge them in the truck bed while driving, including the Jackery. But that can be charged in a standard DC socket. The others need AC.
