Solar panel wiring
I'm rebuilding a Class C and I might be redoing the roof soon. I would like to run the wiring for solar panels now instead of doing it through the fridge vent later. The thing is that I won't be able ...

Get the measurements for various panels then make cardboard patterns and go up there and see where and how many could fit. Just say you could get 600 watts up there, 600 watts is going to give you a max of about 30 amps. If you run an PWM controller you would be carrying more amps than if you used an mppt controller.
If I only knew that I had the potential to put 600 watts up there I would install number 6 uv protected wire through strain reliefs at the frig vent with enough extra up top and down below to reach your possible combiner box and controller near the battery. If you said you can only get 300 watts up there I would then probably use 10 gauge.
If you want to go through the roof you could use something like this but there may be better quality others available. It's just an example of how to go through the roof. Some also go down the vent pipe using strain reliefs.
