Hello, my T314 is 'prepped for solar'. Has anyone installed solar on this or similiar unit? I'd like at least 450 Watts. The company says it will accept a Furrion panel but they won't say if the wiring on the roof is specific to Furrion. Also, I don't want to use the GoPower charge controller. Can I use the existing wiring, if I can find it, with better/more panels?
