The barker great tank's material feels more premium than its price would suggest. It is perfect for a van build. It fits perfectly under the van behind the drivers seat.

Best With Trailer: Class A Customs fuel Tank

It's perfectly for a sprinter gray water tank on the driver side. It is incredibly easy with some plus nuts, a bit of welding and some metal. The tank measures 45"x 8" x 12" and has a slight drop for the run off. The sizing of the tank fits perfectly on the 2019 ford transit, so you can’t even see the tank unless you crawl down under.

The tank must be vented allowing air in and out during use. It is pretty heavy when full. It is recommended to use a fill dish or other gravity process.
