RV Holding Tanks

Our RV holding tanks might just be better than what came with your RV. These RV waste holding tanks are manufactured using rotomold technology, which means that it has no seams, 3/8” thick walls, and is nearly unbreakable. They are to take rough travel conditions with ease. Fittings are spin-welded to ensure secure, leak-proof connections. Simply indicate on the tank drawing where you’d like your fittings placed!
