Hi All, I’m looking at upgrading my solar panels on my Autocruise Select 122, the existing Solar Panel is the one that came on the vehicle which i believe is supposed to be 40w, hence the need for upgrade, what i need to know is whether i could piggyback connections off existing panel and swap out solar controller for an appropriate one, also I’d like to add an additional Battery but Battery box is behind drivers seat and is in snug fit boxing, Thanks
