I'm still getting to know our new 25fb. I was crawling around underneath the AS yesterday, and I have a couple of questions.
The black and grey tanks are covered with a sheet metal box. The fresh water tank is not...I don't think. That is my first question: is this black "tank" a cover or is this the actual tank? See picture
Second question: there is a hole where the dump valve handle extends into the tank cover. It seems road spray could get into the tank cover and I don't see a way for any trapped water to get out. I wondering if I should put a couple of drain holes in the tank covers. In theory that cover could hold a lot of water.
