Now that we are finally camping I can update with the results of some of these mods:
- Sound: the two pieces of fatmat covering the A pillar really made a difference. engine noise and wind noise are greatly reduced (sorry no dB readings, but since we can actually have a conversation without yelling at 70 MPH the difference is noticeable)
- The windshield covers: yes you can see into the RV at night when it's dark out and the inside lights are on--but then you just lower the shade
