Regardless of the diodes if the panel in the middle of the run is in the shade it is going to reduce the current from all the upstream panels going to the controller. Wiring in series helps if you plan to use the manufacturer's 12ga wiring to reduce current loss but otherwise it makes no sense for an RV installation. Shade can come from a tree or even items on the roof like an antenna, refer vent, luggage rack, AC cowl.
