    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.
