    This fits super well over the wheel well of my 2019 Freightliner Sprinter with space for insulation and sound deadening. The plastic is nice and all of the welds seem tight.

    Other models I have seen come with mounting brackets and hardware, I would have liked for this to come with that. Also, I would like to see a video (or a brief instruction manual?!) on how to use the holes provided. I understand how to drill out the holes, but I’m not a plumber and I can’t read minds. I would like to know what each hole’s intended use was instead of guessing.

    Great Water Tank! Fits like a glove in our 2019 MB Sprinter Van. We are very happy with the product and great customer service! Thank you!

    Tanks look great but haven’t installed yet.

    I received the watertank under a week. It looks like a well manufactured tank. This will be going in a 2003 Chevy Express 2500 van and it fits like a glove. I just have to strap it in and it is ready to hook up to my water supply.

    I haven’t completely installed the water system yet. I’ve merely built the dinette benches under which the water tank, water pump/water heater, and interior space heater will sit. I plan to use your spare tire tank for my grey water tank.

    Not installed just yet, but like the quality and size.

    Perfect fit

    Arrived at lightning speed and very well made. Welded up a metal base to secure water tank to floor and side wall. Must have for your Sprinter build.

    Quality product. Thick plastic and well made. Mine came with an extra 1/2 NPT port on the open end. So I changed my plans and hooked up the water pump in front of the tank next to the sliding door. I will suggest they all come that way since it makes for shorter water lines.

  11. John Duddy (verified owner)

    It was exactly what I needed. My only quibble is I’d like 2 1.5″ ports on the top of the tank so I could fill from the top as well as put my check valve there.
