the fabric wheel well skirts were popular 20+ years ago...
and a/s occasionally had left over sets available for many years.
i saw some for a triple in the store 3 years ago.
but suspect they are mostly gone now and would be blue striped fabric.
yes u should still be able order them, either from j/c z/d.
the 'snap' heads (caps) are pressed into the fabric while the snap studs...
are SCREWED into the a/s skin...
yes that's correct.

they do sorta dress up the units when parked but i suspect they do VERY LITTLE protecting the tires from UV...
besides the newest rv tires have MORE uv blocker stuff and should easily last 4-7 years without covers.
if in az a SHEET of ply or some real blocker might be useful...
but the skirts are cool, and expensive.
cheers
