SKU: 000-163-212


70 Gallon Sub-Mount Tank with Boxxer 318

✅ Pure Water Storage: Dedicated to a single purpose: efficiently storing and delivering fresh water to your truckmount. No unnecessary compartments or features.
✅ Maximizes Floor Space: The sub-mount design installs beneath your truckmount, freeing up valuable van floor space for other essential equipment.
✅ Improves Job-Site Efficiency: Reduces setup and tear-down time by providing an integrated, on-board water supply that’s always connected and ready.
Compatible With:
✔ Boxxer 318 ✔ Boxxer 318HP ✔ Boxxer 423s

If you need a place to store your wine glasses, this is not the right tank for you. It doesn’t attempt to hold chemicals, or sprayers, or soda pop cans. It does what a fresh water tank is supposed to do: increase available floor space in the van; reduce set-up and tear down time at the job site; and deliver fresh water to your truckmount consistently and effectively. Can be configured for a Boxxer 318, Boxxer 318HP and Boxxer 423s.
