By the way, for those who want to mount their controller for portable panels back in the RV to be close to the batteries - there's a very easy way to carry along a long and flexible, heavy gage, fairly inexpensive cable to run between the panels located aways from the RV:
Use a contractor-type 10 or 12 gage extension cord available at hardware stores. Make an adapter for it's female end so that the panels can plug in using a regular 120V plug. Plug the other male end into a common 120V receptacle that you wire to the controller's input back at the RV. Use the two hot lines in the extension cord, the 120V plug, and the 120V receptacle to carry the power from the remote portable panels.
We carry a 50 foot heavy gage extension cord along in the RV all time anyway (for rare 15amp/20amp hookups), so I'll use this for the 2nd purpose of running out to a set of two portable panels hinged together for battery charging when drycamping.
