Constant Power for Bed Lights

First time poster here so be easy on me. Truck is a 2016 TRD Sport.

I'm looking to install some waterproof LED strips under the bed rails on my Tacoma and was curious if there is anywhere in the bed where I can find constant power when the truck is completely off. I'm trying to avoid having to get in the cab to click the power button on and whatnot.

I'm running a roof top tent on a RCI bed rack so I want the ability to flip a switch at the back of the bed for light under the tent at any point with the convenience of not having to fiddle with something in the cab in order to do so. Ideally I would be mounting the switch in one of the storage compartments or near the plug outlet in the bed. Any ideas on where to tap into constant power?

Apologies if there's already a thread out there about this. Still learning my way around the forum. Any help would be greatly appreciated. Thanks!

 

No constant power in the bed unfortunately.

Depending on any future electrical projects you foresee, Here's my recommendation

I would buy a 40-50 foot roll of 4awg welding cable (Temco is a good brand on Amazon)
Cut it in half and do two runs from the battery to wherever you think is a good dry spot in the bed
Use this for the positive and negative to the battery for a Blue Seas 12 circuit fuse block.

Now you have 12 fused connections and 12 good ground points for any electrical connections you need. Bed lights, lights in the tent, small fans, etc.
Or do 8awg wire and the 6 circuit. But I'm a fan of doing more than I think I'll need. The cost isn't enough to make up for it.

 

Appreciate the input. I assumed it would probably need to be done this way, just figured I'd make sure first. Thanks again.

 

Aux fux box, wire heavy gauge off the battery, 5 fuses with relay, 5 more just fused, all of them constant on. Ran one to the back of the truck for my bed LED (eventually to be upgraded/improved), others are switched in the cab for front lights, aux reverse, CB, etc.

I bought these specifically because I wanted light in my bed tent. They’re easy to install and are great inside the tent. This is a pic of my set up. Never took a photo with the lights inside of it though

 

I often camp in the back and could use more light. Thanks for the link
