Need recommendations: Drinking/RV/Boating Hose

I buy gallon jugs of distilled water at grocery stores. I use it for my internal use. Coffee, cooking and tooth brushing (or in my case, soaking). Its pretty cheap.
At CGs, I hook up a white hose, but that doesn't tell you where the water in the pipe came from or what somebody (or some dog) did to the tap before you got there. That water is for external use. I'd use a regular garden hose, but I don't want the neighbors to talk. :)
