    Couldn’t ask for a better product to store water. Product and customer service has been top notch. The SPC 20 gl is the perfect amount for my set up for my 2020 AWD Ford Transit 148 Med Roof. No regrets

    Installed in my 2017 Promaster; just needed to create a 3.5″ tall platform around the wheel well and the tank fit perfectly. Threaded ports were all perfect and it’s really nice having the ports on both sides and a big fill port on top. Only issue I had was a strong plastic taste (even after soaking in vinegar water for 2 days), but it is slowly dissipating. May be good to provide some tips on sanitizing and getting the plastic taste out of the tank before install. Still…very happy with the tank and quality.

    Great help from the seller to chose the correct size tank. Fast shipping

    Perfect fit! Great use for the otherwise wasted wheel well space. The custom geometry also seems to help minimize sloshing noise.

    Not efficient use of space in my Ford transit. I will try to return.

    This tank is great. Fits a sprinter perfect and has a bunch of options for connections. Only thing i wish it had were some top connections. The way i setup my bench/counter i have room up top and not a ton front and back so having some 1/2” and 1 1/5 fittings up top would be beneficial in my build

    These are the best water tanks money can buy. Easy to install and reliable.

    great tanks , perfect for sprinter conversions

  11. James (verified owner)

    The tank is great, but I had trouble find the right fittings for 1 1/2″ ports. Also, it would nice to have some markings on the side to indicate water level.

    I used this in my ProMaster, with flooring already in place I had to raise it ~2.5 inches. The tank outputs were in perfect places. I chose this tank over the PM specific tanks because of clearance space in front of the wheel well. Perfect fit, very happy.

    Great tank. Well made.
