OP said,
"This is a rear kitchen unit with batteries up front so I don't have that option."
Why not? It's jut a matter of dropping down thru the fridge roof vent, like others have suggested, then thru the floor behind the fridge, and running cable from back to front, under the rig. All out of sight. Leave the connections at the panels connected at all times.
Size your panel-to-controller wiring appropriately, allowing for minimal voltage drop, using this:
scroll down(For example, I'm running 30' of 6 ga. cable from two 140w panels to controller)
Install the controller out of the weather, and close to the batteries. Include a circuit breaker (or switch) near the controller, between the panels and controller, for opening (i.e; disconnecting) the panel circuit when making adjustments to the controller.
Likewise, wire the controller to batteries with appropriate cabling, circuit breaker, and good quality terminal connectors.
