I don't know if 30ft is enough - probably cutting it close if you're a tree camper. I'd consider putting those panels in series if you go longer to cut down on line loss. Your controller will handle it.
I don't see the need for fusing panels; some do.
If series you can eliminate #2. Size #6 to whatever an amperage chart suggests.
So can the Grape Solar 40 Amp PWM controller really handle those to 120 watt panels in series and still output to charge a 12 volt system battery? I didn't think it could, but you've said yes. If it can, then I would definitely want to wire in series. Thanks.
