I purchased the blue ZeroG hose which is labeled for RV/Marine use. The gray is listed as garden hose but both are listed as drinking water safe. We have the blue in the MH and the gray at home. We like both of them. They are listed as non-kink but only after they are pressurized and kinks removed. They will kink when not pressurized and pressurizing does not always remove the kinks. They are about half the weight of a normal hose and take a lot less space.
