I had panels on my Westie. mounted them to the pop top and went through the top where the wires came out of the panels, then ran them down inside the tubes for the top on the drivers side. Charge controller was inside the kitchen cabinet, battery was under the drivers seat in the factory box. I mounted the inverter on the side of the cabinet behind the drivers seat.
If you want to keep your panel inside the van on your Ford when you're on the move, how about a mount inside the rear doors, suspending it from the roof?
Easy to access, out of the way and protected under way...
