Sally, just remember to pad them a little more than you would on pavement, because in a trailer, the Katy is a monotonous rumble with the occasional bump. I know from experience that the Katy will throw up a lot of very fine limestone dust onto/into the trailer, so please seal it up well.
Since you are in Florissant, you might also consider doing one of the many loops over in Madison County (IL), which are mostly asphalt paved.
