Okay, my Kyocera 135 watt panel arrived Monday. So I'm on the road to getting that solar system set up on my Westy.

My Westy (Syncro) already has an external jack for a wind turbine. I have to alter the wiring slightly to add a switch, so that if Turbine powered I go (more less) direct to the battery (turbine is designed to charge batteries directly and is self limiting) but if Panel powered, I go through a Solar battery charge controller (I have a "rinky dink" 21 amp one, which should be plenty for the single panel.)

In just carrying the panel out to car, though, I think a more permanent roof location is in order, as it is a bit cumbersome to contemplate moving it about all that often. I had already been considering this before it arrived, so this is not really a change in plan.
