    Fits perfectly my promaster. I havent connected it yet but it looks well made and it saved me so much space! It was expensive part of the build but worth it.

  2. Andreas Montano (verified owner)

    This is a really well molded water tank. The walls are think with structural indentations to increase rigidity. I will still have side support in the build, but the quality and available outlets make this space saving water tank well worth it.

    Wonderful, a bit pricey but it definitely is a space saver.

  4. Andreas Montano (verified owner)

    This is a really well done water tank. Very solidly built and it’s perfect for the Promaster high wheel wells (136wb high roof). The shipping was well done and very fast.

    If I build another van I will certainly buy this again – I feel that this tank will last the life of the van.

    I have not installed them yet however the quality is above what I expected.

    This thing is a game changer for space great customer service !

    Well made. Unfortunately I wasn’t able to use it on my 159” Promaster because my water bench would have to be extremely long to accommodate this tank and a water heater. Maybe this tank is better suited for a 159” extended. In the meantime, I’m asking for a return and will be buying a shorter and narrower 30gallon cube – allowing me to keep my bench dimensions (60”).

  8. Eric (verified owner)

    Fits great over the wheel well. The space savings is what makes this totally worth it. I have not yet plumbed or used it but the multiple options for different ports will make setting the system up super easy. Very excited to use this.

    Perfect fit! We’d buy again.
