SEWER LINE AND WIND RESISTENCE
I am new at this, I have researched here and can not find the answers.
My two questions are:
1. Sewer line connected at camp ground. I have read here not to keep open the valve to the black tank. Blank tank should always have water in it. At campgrounds, the sewer line connected to the CG sewer, is this for the grey tank only, and should the grey tank valve be closed most of the time to prevent sewer gas from coming up to the sink?
2. Why, or does some one manufacture an air foil, like those used on over the road tractors, for class C, to move the air over the top of the RV, rather than hitting the obstructions (like the A/C) on top of the RV. Is the A/C such a small item that it really does not resist the air that much?
thanks.
