We have returned from 12 more days of van camping, this totals up more than 50 nights in two years. The new sliding door window worked out great for extra ventilation along with the lithium gen/batt powered fan and our new little dog likes it too. As a temporary solution for this trip I gorilla taped a piece of fiberglass screen over the outside of the window and cracked the front door windows an inch when parked. Light rain was no problem and the air moving in though the side window and out the front windows seemed to keep the bugs out. Even with 99% humidity inside, according to the meter, the van roof and walls remained completely dry, no dripping like in the past. I will find a better solution for the screen and tweak the fan placement but overall this arrangement was a success.
