ML rear step request
 

Would anyone possibly know if there is a subtle rear step or indeed tubular bar that is available to fit below the rear bumper? Besides wishing to provide a degree of protection and enhance the looks to some extent, I am keen to conceal the somewhat unsightly view of the chassis from behind - which is more apparent on my silver ML than my earlier dk blue vehicle.

Any help would be greatly appreciated,

Tokyo Joe.
