Pour 30-40 oz of Dawn Dish Soap thru the toilet with the holding tank about half full and drive that way to your next camp site. 200 plus miles of shake, rattle, and roll will scrub the scum off the sides of the tanks and everything should be back to normal.
Get in the habit of doing this occasionally to prevent the scum from building on the tank walls.

Works also with liquid laundry detergent.
