The Miller Plastics staff has been mobilized in response to Covid-19.

Rest assured, we are fully operational and ready to help.

We are able to create custom plastic RV water tanks in many sizes and dimensions to conform to the specifications of RVs from many manufacturers.

Recreational vehicles, or RVs and campers, have a clean water system and a wastewater system. The clean water is also known as potable water or fresh water; the wastewater is known as black water or gray water. RVs will have separate tanks for both freshwater, black water and grey water.

Our welds are second to none, being very smooth and easily cleaned. Nothing leaves our shop with a saw cut edge or a sharp edge. Every piece of our RV water tanks is individually cut out on high-tech CNC routers. Scroll below to get a quote on a custom RV water tank today.

These custom fabricated tanks start at $1,491.
