Open trailer towing

[Arcticdude]

I've got a specialty vehicle that I think I'd like to use as my toad on some occasions. It's not something that's flat towable, nor would I want to make it so. Those of you that use an open trailer, how dirty does stuff on the trailer get when you tow it? Does stuff take a lot of abuse from road debris? My normal toad does get some abuse from debris getting kicked up by the coach, but since I drive it a lot of the time as a daily driver it's gets beat up some anyway.
