The Spray-Port can also be utilized, with or without a cover, in baggage compartments and /or under the hood of large motorized RV’s. For maximum versatility, place a Spray-Away storage unit on one side of the RV and a Spray-Port hook-up on the other side. Requires the Quick Connect Coil hose #SA-HOSE-15-ASYR or SA-PT-ADPT Quick Connect Garden Hose Adapter (both sold separately).
