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

Culinary grade matcha. Its okay for mixing in small amounts with other flavors to drink
Flavor Name: Culinary Matcha-3.53oz
I ordered this Matcha for the affordability. The matcha I’ve been drinking is more expensive and as I have been drinking more Matcha lately I wanted to try to get more for my money. Now, I don’t want to sound like a Matcha snob, but I really wasn’t happy with the quality or the taste of this Matcha. It was lower quality than I was expecting. First of all it’s a duller green color, which is just appearance I understand and I can overlook that, but it says something about the quality of the harvest. The taste, however, is much more bitter than I am accustomed to. Not an enjoyable clean Matcha flavor. I have found that it absolutely needs some sweetener and milk to make it passable and I’ve even mixed a little cocoa powder with it to mask the dusty flavor. That helps. Also, it is not ground very finely as other Matcha powders. I can feel the Matcha particulate in the tea when I drink it and it settles to the bottom of the cup very quickly. If you’re going to be cooking with Matcha, then this is fine. Or if you are going to be mixing it with milk and sweetener or other flavors, then this isn’t too bad. But if you like to enjoy the pure flavor of Matcha tea with nothing added to it then I would not recommend this one, it’s pretty harsh. Still, it is very affordable and it can get you through when money is tight.
