I just purchased a 13' Trillium
last week and I immediately headed out on the road. It was hot and I was advised not to drive with the windows
open. I considered the advice and could understand having the front or side windows
open could impose stress on these windows
that could cause damage but... Hmmm, the rear windows probably would be safe from these so I tried opening them just a bit. To promote circulation I opened the roof vent slightly also. Following my GPS to find the shortest route home provided a few surprises; dirt roads.
Upon arriving home, I entered the camper to survey my little gem and... there was dirt and dust on everything! The dust cloud
created on the dirt roads was sucked in through the rear window and the air circulation I had hoped for had been present and worked against me.
Soooo... I won't drive with my windows open, especially on dirt roads.
