basic solar diagram
I'm a bit dyslexic when it comes to electrical issues, so I need better eyes to double-check my work here. I'm adding solar panels and extra batteries to my rig and I'd like to be sure I have the con...

That chart is not good for your application. You should be looking at cable that has 1% voltage drop.
Regarding fusing panels: It's impossible to fuse 1 or 2 parallel panels. Three or more panels can be fused. If you have 3 or more panels then each panel gets a fuse. If the short circuit current of the panels is 5A then the fuses should be rated one size greater than 5A.
When you combine all your parallel panels to one wire going to the charge controller, it's worthless to fuse this wire. It's however important to have a panel disconnect switch. If for some reason you disconnect the batteries, you do not want panel power going into the charge controller. Panel power needs to be removed before battery power.
