Slant Load 18 Water Caddy allows you to take 18 Gallons of fresh water with you on your next road trip and fits conveniently in the corner of your walk in tack room utilizing the "dead space" in the corner. The SL-18 is a perfect alternative for those trailers that require a smaller "foot-print" than the SL-25 or SL-39. We manufacture it with FDA approved Polyethelene so the water is safe for you and your animals to drink. Transulcent poly allows you to easily check water levels in the tank. Fill cap is located on the very top middle of the water tank. Two molded in aluminum 3/4" drain inserts ensure the drain attachment spot will never break, sunrot or fail. Two 3/4" shut off valves included. The top shut off valve allows for filling a bucket with out needing to attach a hose. The bottom shut off valve allows for draining all of the water from this tank. The strap kit provided makes installation quick and easy.
