I have seen several threads extolling the virtues of the new style of Rockwood front windows without the plastic/fiberglass cover. On our most recent trip down to Charleston and Beaufort SC the love bugs were CRAZY. At several points it sounded like rain on my windshield. The front of the truck was covered to the point where I actually wondered about airflow to my radiator.
I took a picture after we arrived in Charleston at the Mt Pleasant KOA and I thought it looked like a great argument in favor of the screen.
