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.
