For example my Bogart sc203 solar controller was $160. Each 130 watt panel was $155. I see no reason you couldn't wire the controller through anderson connectors. The panels could be removed from the mounts that are more permanent on each RV's roof. Panels use mc4 snap connectors. Many various install ideas in this link. I always disconnect the solar panels from the controller BEFORE disconnecting the battery.
The bogart trimetric system monitor does connect to the solar controller for full system tuning. The sc2030 solar controller will work without the trimetric but you get a set charging profile. For that reason you may want a stand alone solar controller with fully adjust ability for charging voltage adjustments and equalization.
