I was inquiring about running a 6awg wire from the truck battery to my (someday) new hawk flatbed and asked what they do at the factory.
They replied that the internal wiring inside the camper is 10awg; which they use from the truck battery to the camper.
If that's true, the only benefit I can see is that there might be a slight voltage drop from the truck battery to the camper but after that, it won't matter.
Calculations for a 15' run @ 6awg, 10amps is a .4V loss.
Calculations for a 15' run @ 10awg, 10amps is a .98V loss.
So, you lose about .5V using 10awg.
Since I don't know how they do the connections on a Flatbed (or how they do it now vs. my 2001) I imagine that the wire comes into the flatbed and into a fuse box where it splits off to the house battery and electrical components in the camper? If that's the case, you could upgrad the wiring to where the fuse box is and then upgrade the wiring to the battery.
I'm leaving off the DC-to-DC charger, etc. for ease in this discussion.
