I bought it from my overland trailer. 7 gallons is perfect. I wanted to have on demand water. Instead of bringing bottles or cans of water. I have a roto packs that I'm out on the side of the trailer I will still continue to use the water container for that but it's just nice to have that on demand versus having a jug that you got to pour out of. The construction seems fine. There are little fragments of plastic inside of it but basically I just flushed it out with water. There's three threaded inlets plus a inch and a half inlet which I did not use. The three threaded inlets I just bought an adapter at home Depot. One runs a hose for the air. The other runs into The door that I have mounted on the side of the trailer for the water going into the tank. The other one runs from pump to the tank.
