Made with BPA-free, food-grade (CSA approved) polyethylene, not only do these tanks save space and provide a good amount of safe drinking water, they also insulate your wheel well to keep the road noise down.

Looking for a grey water tank to compliment your freshwater tank? Check out our 15 Gallon Promaster Undermount Tank! The undermount tank fits snugly under the passenger side of your Promaster’s framed undercarriage; the perfect solution for your off-grid water requirements.

Key Features & Benefits:

  • Space Saving - A unique way to make efficient use of that awkward wheel well area and shape.
  • Perfectly Shaped - Not only do these tanks mold to the shape of your wheel well but the top and outside are also squared off to account for further building. Last we checked, it’s easier to build a square box than a round one.
  • Build Options - These tanks are interchangeable between both wheel wells; you can fit this tank over whichever wheel well works best for your build. Need more water? Place one on either side of your van for mega-volume!
  • Distributes Weight - Adds weight over your rear axle to help increase traction if you get in a sticky spot. No more slips and skids, not to mention unwanted wheel wear, thanks to the perfect weight distribution of these tanks.
  • Sound Proofing - When it comes to road noise, these tanks step it up with added noise reduction around your wheel well.
  • BPA-Free and Food Grade Approved - Feel safe knowing these tanks are food grade CSA approved! Wash the dishes, have a shower, fill the dog bowl, and stay hydrated, while exploring in your van!
  • Fittings Kit Add-On Available - Save yourself the headache and multiple trips to the plumbing store when you bundle this tank with our Freshwater Fittings Kit!
  • Strapping Kit Add-On Available - Weather-resistant strapping crafted from heavy-duty 1/8" thick, 1 1/2" wide aluminum. Simple and secure! 
  • Water Level Sender & Gauge Kit Add-On Available - This water tank has a fitting specifically designed for use with the KUS S5U Water Level Sender!
  • Compatible - Pairs well with our 15 Gallon Promaster Undermount Water Tank

Size seems spot on shoe is beautiful
Size: 12, Color: White
These are beautiful shoes. A great cross between the ubiquitous flat as a board shoes like vans and tennis shoes. More comfortable than the super flat shoes and more formal than sneakers. Very soft leather. Not much arch support and I don't know if an insert would fit well. I am between an 11.5 and 12 in most brands (actual foot length from heel to tip of big toe is 11 and 1/8 inches). These fit perfectly in a 12 with room for comfort. An 11.5 probably would fit but snugly. I do not agree that they should be sized down at least based on my experience. If you can get these for under eighty dollars like I did they are well worth it. I'll be wearing them all summer.

Weightless, well made. But there are problems with size
Size: 8.5, Color: White
I bought it for a teenager, for size 81/2. This, according to the dimensions on the page, is 25.9 centimeters. They came, the size was indicated correctly, but they are large for the child. Very large. They fit me, size 10. The child is disappointed. Well made, look neat on the foot. Almost weightless But I can't give the maximum rating. I wish the seller to deal with the size grid.
