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. Review: Nice plastic box - So far so good! Haven't had it terribly long but no leaks yet and seems to be well made. ## Features - 7 Gallon Fresh or Gray Water Holding Tank Manufactured by Class A Customs - Made from NSF Approved Materials - Fresh & Drinking Water Safe - Can be used for Fresh or Gray Water Storage - WATER TANK MEASUREMENTS: 23.75” Longest Length (not including fittings) x 7” x 9.75” - Tank can sit on any side - rotate tank to change height or width Average Thickness 7/32” +/- Please view photos.
