Review: Works great for our camper. - I recently ordered the 16 Gallon RV Fresh/Gray Water Tank (24" x 15" x 10") to replace the tank in our camper, and I couldn’t be happier with our choice! Right from the start, this tank impressed us with its quality and performance. The size is absolutely perfect for our needs. It fits seamlessly into the designated space in our camper, and we had no issues fitting it into place. This was a concern for us, as we wanted something that would not only work well but also fit snugly without any modifications. Installation was a breeze! I appreciated how straightforward the process was, with clear instructions that made it easy to hook everything up. Within no time, we were fully operational and ready for our next camping trip. The tank’s design allows for easy access to all necessary attachments, which simplifies the installation process significantly. Durability is another major advantage of this tank. It's made from BPA-free materials, which gives me peace of mind knowing it's safe for fresh water use. The construction feels incredibly sturdy, and I’m confident it can withstand the rigors of camping trips, from rough terrains to temperature changes. Overall, I highly recommend the 16 Gallon RV Fresh/Gray Water Tank to any RV or camper owner looking for a reliable and high-quality replacement.

## Questions & Answers

**Q: Can it be used for gas storage**
A: Gasoline containers have strict guidelines mandated by the EPA. This tank would not meet the guidelines for gasoline storage and it has not been test for that purpose.

**Q: Can you install by standingthe tank up**
A: We carry it around in the back of our truck and hook it up to camper by water hose and pump as needed. Not sure where you are installing it

**Q: With the drain being on the side of the tank, will all of the water drain out? It looks like some would remain pooled at the bottom?**
A: If there is any that can’t reach the drain, I ouck it up a little to get it all out. So, yes. Some does pool. Not much though.

**Q: What glue to use to add my own hose connection?**
A: We use a pipe and hose clamp because we don’t know what type of plastic it is.
