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

Great pans for meal trains or prep
Size: 10P -9×13 In, Color: Silver
Great pans for delivering meals to people or prepping freezer food. Four stars because they are slightly smaller than a 9x13 pan, but they still work great for most recipes. They are much cheaper than the stores.

Pleasantly Surprised

Reviews for this product were varied, but I decided to give it a go. A wise choice. These arrived on time, in a plastic bag, in a box, inside a sturdier box…in perfect condition. They are very sturdy compared to most I’ve seen. I used them in preparing a meal for a family who lost a loved one. If they easily accommodate 5 lbs of potato salad, I’d say they’re sturdy. I also used them for sliders, and a couple of fruit trays.

Fantastic
Size: 20P -8 × 8 In w/ lid, Color: Silver
I bought these while making a small army of casseroles and freezer meals for family memberhaving surgery. They survived being filled, carried, stacked, transported, and generally treated far less gently than they probably should have. The lids fit well and were worth their weight in gold. Not having to battle aluminum foil every time I needed to cover a dish was a welcome bonus. The lids stayed put. The pans were sturdy, traveled well, and were the best price I found for covered 8x8 disposable pans. Sometimes the boring kitchen supplies end up being the most satisfying purchases, and this was one of them. I'd definitely buy these again.
