I did 10/2 on mone and in retrospec was probably overkill. It was recomended by e trailor , but when i hooked it up it was a bit harder. If i was to do it again i would go with a smaller gauge wire.make sure you get stranded wire. And i also ran it outside the tube. Fixed my low power to my break controller issue. And its not a hard job.

I would assume one wire per wheel if using #10. So 10/2 for two axle, 10/3 for 3 axle.
I don't recommend parallel wires, just use the right size.
Yes needs to be stranded to flex with the suspension.

Excellent guys thank you for the advice. I was talking to a friend of mine and he experienced similar on his car hauler. Of course the wires were within the axle and rubbed through.

I will report with my findings.

You just need 2 wire. Run it back where you can and branch off. You could run it stright down the middle and do equal lengths. But i didnt, just went to one side then branched off to the other. The volt drop will Not be noticable. I atually followed what was on my camper to begin with, but my 10 wire was way bigger then what was originally run. I have a dual axel for reference.

I had a broken wire underneath my Toy-hauler by the brakes themselves so only one side was braking.

Wanted to update you all incase someone finds this post in need of help.

I went through the system with a fine tooth comb and the culprit was inside two tubes. It seems that WW used really nice 10AWG shielded wire up until it splits into the tubes.

From there it seems like they used cheap speaker wire and of course two sections had rubbed through.

The crappy part was I also replaced my brake controller with a smart updated Tekonsha controller, well long story short the brake controller sensed the short and completely disconnected the brakes all together for the ride home. This made my 25 mile trek in stop and go freeway traffic a little sketchy.

I rewired all three axles, wrapped and secured everything including all wiring on the frame rails and it did the trick.

Thanks for all the advice

I had some work done by a local suspension shop, had to replace an axle, they found the same thing.
Replaced all the wiring with good wires ran on the outside of the tubes.
My brakes have never worked so well.
