Here is a link to the Zamp website outlining the possible setup:
Solar Ready RV Solar Kits - Zamp Solar
"If you see a sticker that says the RV or Camper is ‘Solar Ready’ then that RV has had the Zamp Solar port(s) and the wiring pre-installed. There are two main ports that are being installed on RV’s – a single Zamp Solar Port and a Zamp Solar 3 Port Roof Cap. If either of these have been installed that camper can take advantage of our SRRV kits that have the required equipment to harness the power of the sun."
