Traveling along west Texas there’s a very windy section of highway near the I-20 and I-10 junction. Last year it laid waste to a cracked spoiler on my GMC Sierra, this year it claimed the shroud on the roof air conditioner unit. I’m sure it was brittle, but it got shredded! We heard a bang and whistling in the front of the RV, we pulled over and I walked the perimeter but did not look at the roof. Next morning after we got home we found out, holy cow! 🙂
