It's a dual battery but I'm pretty sure there's a couple of big lugs on the outside of the fuse block I can use instead.

Is it worth running a ground wire too or just use the frame?

PS: hard to post these days - I have to log out to see the forum at all; then I have to log back in after I click reply to topic. Odd that it doesn't affect every forum. Other people are having the same problem.

Most of fuse boxes have main wire rated for over 100 amp, but if you draw 40 amp for tool and use other accessories, that might be a concern.
It is just easier to add additional cable to battery clamp and put circuit breaker on the line.
This is how I wired 1600W inverter on my camper, where 100amp breaker has a switch, so easy to keep it off and turn on only when needed.
Bear in mind that hot wires run under the bed are higher-risk issue, so plan to put them in additional sheeting.
I had several issues on frame-bolted ground wires.
Corrosion gets to them and lack of power is hard to troubleshoot.
Manufacturers do it, but they hope the truck will come out of warranty before the corrosion-related issues will become reality.
I have no problem with forum script.

Curious to know what kind of breaker you got with a switch.

Also, 100A at 12V doesn't fully power your 1600 watt inverter.

The breaker never tripped with my cappuccino or microwave.
Here is 200 amp in the same design.

OK that's one of the ones I found. Do you push the red button to trip the breaker then later use the lever to set it?

With 12 volt, you have have a lot of current loss with length. How about adding batteries to the bed and tying them into your rv charging system?

Yes, that's how it works.

If your expecting a high amp draw you need a whole separate power feed from your electrical system. I installed a 17,500 lb. winch on my 2002 F350. I will include a picture to give you some ideas how to supply power and isolate. Here’s a quick list of materials I used:
•Blues Seas Disconnect- rated 500 Amps
•Spartan ANL fuse holder- I have fuses ranging in 200, 300, 350, 400, 500 depending on my use: winch or inverters.
•2/0 welding Cable
•Quick disconnect plugs

Check your wire size and Ampacity and resistance drop for your length of run from your battery to your bed.

I did this on mine and added the disconnect as a safety function in case of front collision.

And here is a link to the Ampacity chart- it is for Marine use but actually they have stricter codes than Auto.
