Zero Declination is awesome! Just returned from there myself after getting electrical and lithium upgrade for my FWC Fleet. KP installed 4 awg wiring and all Victron components (DC-DC charger, BMV 712 battery monitor, and MPPT solar controller). He's worked on thousands of FWC's and knows them inside out. It was absolutely worth the drive to Reno for his expertise and competence. I highly recommend.
