I'd rather not do much rough field stuff with her. I have, however, seen a Cherokee Six at our FBO with some surprisingly large rubber, so
I'm guessing there's been some thought on the matter.

As I'm really enjoying the 'kee, which is a rental, I'm attracted to the bang-for-the-buck of some of the lesser PA28 models, and have read some
interesting mods which seem to make it a decent short field machine.
The most obvious concern, if there's a bunch of FOD (gravel, etc.) would be the wings and flaps. Fortunately, most of the little fields I'd care to
use around here are well maintained grass without a bunch of junk in it. I do like the ability to make an emergency landing in a short space, though,
even if I do ding up the sheetmetal a little.
One site that seems to have a little on the subject is http://www.pipermods.com/
