Does anyone know what is included in the Rough Road option for the lower two spec cars (S and SE, see below) which is included apparently as standard on the SEL and above?   Reports suggest its additional under-body protection which could well be helpful for me but my new SE seems to have complete albeit flimsy  plastic trays underneath and I can't get into a dealer at the moment to try and get a look. A photo if possible would be very helpful; thanks
