Solar Port Ray,
The 30 A trolling motor plug might be the answer. I already have a 30A RV port at the front to power the trailer with the genset in the truck bed, and did not want a similar port tied to 12V solar. Is your 30 A cord soldered to the solar panel or does it mate with MP4 connectors. I will need a disconnect between the 30 A cable and the panels for storage. Thank you for always sharing your knowledge and experience.
Bill
