That's a good way to get one set of cables through.
I ran multiple cables for power and two way radios so I did end up pulling the wheel well cover off after fighting things for a bit. Pulling all of those cables through was not working for me
I didn't want the power cables to be allowed to chafe against any sharp edges as the truck bounced around off-road. Now the cables are all ty-wrapped securely to the body of the truck.
Here is what my modified power panel looks like now.
The DC power comes from my second battery and is always on. I changed the Engel fridge from a cig lighter plug to a Power Pole connector which makes far better electrical contact and does not easily come loose.
