Review: PERFECT - We had a custom tank very close to these dimensions quoted to us for around $430. I was nervous about ordering this one, as the price point is totally awesome and you just never know what is going to arrive in the mail with cheaper items. But it is PERFECT. It is quite honestly just as good as the other custom tanks we have ordered in the past constructed of the same material. I am so, so glad that I found this freshwater tank on desertcart-- it literally saved us hundreds of dollars! And it works famously in our school bus conversion. Definitely would recommend this!!!!
Review: Great product & priced to sell - Great product & priced to sell ! I got tired of always running out of water so I simply removed my old 26 gallon fresh water tank & installed this one under my bed in the RV. I'm buying another one for the sewage too. Although they're well constructed I added plywood side walls to lessen the bowing out under the water pressure weight as advised by another customer here. The RV companies never put big enough tanks in.

## Questions & Answers

**Q: Can this tank be standing up with outlet facing down ?**
A: You would have to drill holes in whatever you were going to set the tank on to allow for the fitting to go through and you will need to brace the tank.I can only verify information for the water tanks classAcustoms sells.Item is made from DOWTM DPDA-3135 NT 7 Medium Density Polyethylene (MDPE) Resin that is Long term UV-8 stabilization. For more information go to classAcustoms blog and search water tank information.Tank will need to be properly vented and braced.Non-Pressurized Tank - you will need to vent this tank to use it. Do not hook garden hose to tank.Tank will need to sit on a level surface and be braced.Do not place weight on tank.Includes 4 fittings built into the tank - ALL fittings are on one side:Two) 1 1/2" Dia screw in balloon fittings (threaded female - NPT Standard) The fitting will be closed off an can be used or left as is. To use the fitting simply trim out the inside piece.Two) 1/2" Dia screw in fittings (threaded female - NPT Standard)Measurements for Tank: (+/- .25" on each measurement):42 1/2" Longest Length (not including fittings) x 14" x 18" (rotate the tank to change height or width)Average thickness: 7/32" +/-

**Q: Can this be used outdoors like a rain barrel with some modifications? The spot I have will not fit your typical rain barrel.**

**Q: what is the thickness of material used, and the warranty period?**
A: These are not tanks you can pressurize you would want a metal tank.This style of water tank must be vented allowing air to move in and out when filling and emptying the tank.You should NOT fill the tank from a direct city line (garden hose), this is not a safe option and could explode the tank causing serious damage.You will need to leave one fitting free to allow air to go out of the tank when being filled with water and air to go into the tank when being emptied of water. The easiest method is to use an outside fill dish.All tanks will vary on thickness but on average these are .219 or 7/32" thick. The tanks will need to be braced and sit on a flat surface. Tanks should not have anything set on top of them

**Q: I see two ports in the top, are these meant to be cut out as fill ports?**
A: Two) 1 1/2" Dia screw in balloon fittings (threaded female - NPT Standard The fitting will be closed off an can be used or left as is. To use the fitting simply trim out the inside piece.)Two) 1/2" Dia screw in fittings (threaded female - NPT Standard - The small hex head is a temporary fitting that is put into the tank during testing to check if the tank is water tight, we don't recommend keeping these in but if you do be sure to use a food safe pipe dope to keep them from leaking.)This style of water tank must be vented allowing air to move in and out when filling and emptying the tank.You should NOT fill the tank from a direct city line (garden hose), this is not a safe option and could explode the tank causing serious damage.You will need to leave one fitting free to allow air to go out of the tank when being filled with water and air to go into the tank when being emptied of water. The easiest method is to use an outside fill dish.You will use one fitting for water to flow in (from fill dish) and one fitting for water to flow out (to sink) and one fitting to vent the tank. Have a certified technician install all parts to prevent product damage and personal injury.

### ⭐⭐⭐⭐⭐ Perfect for boon docking
*by K***N on March 21, 2016*

I installed this 46 gallon auxiliary fresh water tank in my motorhome in addition to the factory 90 gallon tank. Now with 136 gallons of fresh water, I really have a piece of mind when out in the middle of know where for long periods of time. We always fill up at the last water stop just before we arrive at any destination, so weight and fuel mileage isn't an issue. It was very simple to tap into suction side of the water pump and install a couple of diverter valves. You can never have too much water when dry camping. Thank you Class A customs.
