Thanks for the nice build report.
Where does the water go that runs down the tent fabric when open?
Currently, as it sits. It would get into the tent. But we live in California and it won’t rain here till December. When the weather hits, I am taking the camper off and redoing the fabric. It will have a “rain skirt” type of flap that will come from the tent and overlap the 80/20. Thus allowing the rain to go off the side.
