My question is the pre solar wiring installed from the factory seem too small.
Has anyone ran new wiring down into the bay? How hard was it to fish down?
I'm going to mount my controller on the wall between the propane tanks & the underbay storage. My extra two batteries will go there also.
Your factory 10 AWG wire should be adequate assuming you are going to parallel the panels - you will have about 21 volts at 19 amps.

Look here for wiring calaculators.
