Review: RV Fresh and Gray Water 30 Gallon Tank - I have ordered from Class A Customs before a 10 gal tank. This 30 gal tank is just as sturdy as the other one. People complain that the tanks have plastic inside no big deal it is part of the manufacturing process. All you have to do is run a vacuum hose in the tank and suck out the shavings. Class A always ships out their product in a timely manner. These big tanks can benefit from some support on the sides but if you're going to mount in a trailer you have to support it anyway to keep it from moving around when you are traveling so no big deal either. You don't want 300+ pounds of water moving around. These are a great product, and I would recommend them to anyone needing a water tank. Review: Outstanding Value - Installed this tank in a 35' cabin cruiser to replace an old galvanized steel tank. The tank came in great shape. I found none of the defects or debris that some others have noted. The tank is very sturdy and the fittings worked great. Given that I've been quoted 5-6 times as much for tanks from other sources, I'm very pleased with the price and quality construction. ## Features - 30 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: 34.5” Longest Length (not including fittings) x 12” x 17.5” - Tank can sit on any side - rotate tank to change height or width Average Thickness 7/32” +/- Please view photos.

Need exact weight for a build** A: This question makes no sense...The tank holds 30gal so that's 249.9 lbs.. Whatever you build better be able to hold a lot more than that.. **Q: do you know if is fine if i hang this 30 gal. tank with 2 metal straps 1.5 inches wide from the chassis of the truck ??** A: Yes, you will need to enclose the entire tank and brace it letting it sit on a level surface such as plywood or sheet metal. Be sure you check clearance to avoid having the tank removed on a speed bump or curb. Do not hang the tank under the trailer with straps, enclose tank on level surface.Food Vendors: Some states require your gray water tank to be placed outside of your trailer for safety reasons. This varies by your local health department, we do not know this information, check on this BEFORE ordering. **Q: How many gallons per minute will flow out of this tank?** A: It depends on your pump more than the tank. If you use the 1-1/2 inch hole you can pretty much drain it gravity in 90 seconds. Pulling it down with a large pump then you could probably do it in 30 seconds. ## Customer Reviews ### ⭐⭐⭐⭐⭐ RV Fresh and Gray Water 30 Gallon Tank *by C***N on January 14, 2022* I have ordered from Class A Customs before a 10 gal tank.
