This is a 20 gallon undercarriage tank for the passenger side of a 2015-2026 Ford Transit on the 148" or 148" EXT wheelbase. It rides under the van, so it adds water capacity without taking up cargo space, and it can serve as either a fresh or a grey water tank.
S&B makes its tanks in-house and pressure tests every one. The material is food-grade safe, BPA-free polyethylene. The tank is TEI listed and RVIA approved, which matters if your build needs RVIA certification.
Tank dimensions are 59" L x 15.86" W x 10.55" H, and S&B notes they are approximate and can vary by up to .5".
Fitment
2015-2026 Ford Transit, 148" and 148" EXT. S&B lists it as working with factory Transit and Transit Trail running boards.
Install notes
Check that nothing is installed in the way of the tank before ordering. S&B says it works with factory running boards and Owl running boards, and does not work with Flatline running boards.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
