We are in the process of purchasing a used 2011 Zinger ZT26BH. While inspecting, we noticed that there are two low point drains, one red, one blue,under the unit. Then just about 6 inches in, there is another red line hanging down. Since our previous campers only had the two, I am wondering if this is from the factory or a modification as well as the intended purpose. The salesman doesn't know the answer. Can you help solvethis mystery for us before we finalize the purchase.
