S&B 39 GALLON WHEEL WELL WATER TANK FOR 2013-2024 DODGE / RAM PROMASTER 1500, 2500, 3500 136", 159", AND 159" EXT (BOTH SIDES) - 10-3018

S&B 39-gallon fresh-water tank for 2013-2024 Dodge / RAM Promaster 1500, 2500, 3500 136", 159", And 159" EXT (both Sides). Engineered to bolt into the wheel well for a clean, OEM-style install that adds serious water capacity for overland, van-life and work-truck builds.

Why upgrade? S&B water tanks are vehicle-specific — shaped to use otherwise wasted space without compromising ground clearance or cargo room. The result is a low-profile, sealed reservoir that survives the road just like the truck it's bolted to.

• 39-gallon usable capacity
• Vehicle-specific fit using existing mounting points where possible
• Cross-linked polyethylene construction — UV and impact resistant
• NSF-compliant for potable water (verify with your installation kit)
• Compatible with S&B mounting hardware and plumbing accessories
