Claim the unused space under your slider door without drilling a single new hole in your floor. This tank mounts between the Sprinter's frame and the passenger-side slider door step cutout, using otherwise wasted undercarriage space. Ideal as a dedicated grey tank paired with a larger fresh water setup, or used standalone for fresh water.

⚠️ Gas engine Sprinters: The exhaust runs closer to the frame on gas models. A heat shield (not included) should be installed between the tank and exhaust before use.

About Vanlife Outfitters

Curated products and expert guidance for DIY van builders

Vanlife Outfitters started as a blog chronicling our founders' DIY camper van builds and has grown into a trusted one-stop shop for van conversion parts, curated by people who’ve built the vans and lived the vanlife ourselves. We only offer road-tested products we’d use in our own vans, and pride ourselves on fast shipping and world-class support. It’s not just about the gear - we provide expert-built guides, pre-purchase advice, and real support long after your order arrives. Built by vanlifers, for vanlifers, we’re here to help you build with confidence and enjoy the freedom of life on the road.

I’m happy to give a shout out to VanLife Outfitters. These folks are an incredible example of how a company should conduct business. Although I’m building a truck camper, I have bought several things from VanLife outfitters and their customer service is bar none . I would never hesitate recommending VanLife outfitters to anyone whether they are building a van camper or boat. And I might add even a tiny home. Everyone that I’ve talked to have been nothing but incredible. In particular, Jason in technical support was an incredible blessing to me. I had a problem with the Aqua Hot Gen 1 heater I bought from them. It was not the heater fault, but something I did. Jason helped bird-dog the solution and together we got it fixed. He stuck with me, did research, and called me back several times to make sure that the problem was resolved. These people know the business, many have their on rigs, which gives them the best experience. Thanks you Vanlife Outfitters!!!!

This company is amazing! Quick shipping, best price possible. Customer for LIFE! Thanks Vanlife!

My husband and I are doing our first vanbuild. As rookies, we have found Vanlife Outfitters to be a trusted resource for ease of product shopping and purchasing, video demonstrations, guidance and excellent customer service. They were particularly a great one-stop shop when building our electrical system.

I ordered most of the parts for my sprinter conversion from them. They have absolutely the best customer service. I had issues with my fridge installation duing the weekend and eamiled their customer service for help. Both times, they emailed me back with the instructions/help I need on Sunday. Thank you and this is absolutely my go to place.

Spent lotsa money here, will probably spend more. High quality products, fast shipping and tremendous support. Excellent free resources, e.g. wiring diagrams, on the website. Highly recommend.
