I have an 11 gallon solar shower that fits nicley in the cargo area over
the cab on my dads or sisters Westy. howerver I have yet to get a rack to fit
 over my Adventurewagen hi top to hold paddleboards or surfboards or
kayaks.  I thought if I did I would put a basket way up there to hold the  90
pounds of water.  I have used battery powered pumps that go thru twice  the
amount of water as gravity does.  With the Westy solar set up my wife  and I
take turns sitting in a chair in a bathing suit while the other holds the
shower head.
