Bed plug limitations?

Is it possible to wire my custom camping shell using Romex (just basic lights, switches, and receptacles.) and wiring it all into a male plug end that I could just plug into the bed. I'm thinking it would be too much for just the bed plug but I don't know much about it so wanted to check here.
Thanks

 

Sure. Just add up your loads and size wires accordingly. Assuming no heavy users your are probably looking at under 10Amps.

 

Are you talking about using the 110v inverter plug in the bed to run lighting in your camper shell? You'd need to leave the engine running to get any more than 100W. And even 100W would run your battery dead pretty quick.

What's your real use case? Camping overnight? Short day use?

 

My ideal use of for camping like temporary having it on at night or during the day to charge things sometimes or power lights. and i would usually just run the truck so the battery doesn’t drain or get another battery. But so how many amps can i put on it and how to i calculate how many watts or amps the wiring is going to use?

 

With engine running, you can use up to 400w of power at the 110v outlet. The calculation is Watts = Amps X Volts. 400w / 110v = 3.63a.

I'd highly recommend getting yourself a lithium power station. My personal preference is Bluetti, but there are multiple good brands, such as Ecoflow. I wouldn't touch a Goal Zero ever again. I previously set up my truck with two extra "house" batteries, and it worked great for 12v lights, charging USB stuff, and running a fridge. When pricing out a new build, I found it easier and cheaper to just do an all in one power station.

 

With just lights and charging stuff you'd probably be hard pressed to "max out" the bed outlet itself at 400W but any tools/appliances with heating elements or electric motors you definitely can. The issue would be more draining your main battery if you aren't careful about how much you're using, the truck battery isn't meant to handle being drained way down and re charged frequently.

You'll want to add up what your lights, charger etc. would draw to get a rough idea of how much you'd need for battery or how long you can safely draw off your main battery, which generally isn't good practice. Look up tools to calculate it or just do the math by hand with P=IV and V=IR etc

 

Thanks for the great info. Just curious, why will you "never touch goal zero"? I had been looking at their stuff and it seemed pretty nice and I had heard a few good things from people.
