RV Fresh Water Tanks

Our RV water tanks might just be better than the original.  Manufactured using rotomold technology, this fresh water RV tank has no seams, 3/8” thick walls, and is nearly unbreakable.  It’s made to take rough conditions and travel with ease.  NSF and FDA complaint materials are used in the manufacturing process, ensuring safe drinking/potable water storage.   Fittings are spin-welded to ensure secure, leak-proof connections.  Simply indicate on the tank drawing where you’d like your fittings placed!
