You talking about the decorative trip piece that hang down low under the RV?
Mine was crack from the dealer (only took a year to get the free replacement one) so in installed myself (very simple).
I saved the old one. I though about cutting it down about 2 inches... I think it would look fine trimmed down....And save my new one for when I sell the RV. But when it was off it looked too naked.
