Buying Guide for a 100 Gallon RV Water Tank

Understanding My Needs

When I first decided to upgrade my RV water tank, I had to consider my personal needs. I thought about how often I camp, whether I have access to water sources, and how many people typically join me on my trips. A 100-gallon RV water tank seemed like a perfect choice for my adventures, striking a balance between capacity and weight.

Material Considerations

I learned that the material of the water tank plays a crucial role in durability and weight. Most RV water tanks are made from either polyethylene or stainless steel. Polyethylene tanks are lightweight and resistant to corrosion, while stainless steel tanks offer more strength but can be heavier. I had to weigh the pros and cons based on my RV’s weight capacity and how often I’d be moving.

Size and Fit

Before purchasing, I measured the space in my RV designated for the water tank. I realized that while a 100-gallon tank sounds appealing, I had to ensure it would fit comfortably without compromising other storage areas. I took precise measurements, including height, width, and depth, to avoid any surprises upon installation.

Installation Process

I considered the installation process, as I wanted to avoid a complicated setup. Many tanks come with installation kits, but I needed to assess whether I could install it myself or if I should hire a professional. I watched a few tutorials and read user reviews to gauge the difficulty level and ensure I had the necessary tools.

Drainage and Maintenance

I paid attention to the drainage options available with the tank. Having an efficient drainage system is vital for maintenance and cleaning. I looked for tanks that offered easy access for cleaning and draining, as this would save me time and hassle in the long run.

Weight Distribution

As I considered the weight of a full 100-gallon tank, I realized that weight distribution in my RV is essential for safe travel. A full tank weighs around 800 pounds, so I researched how to distribute this weight evenly throughout my RV to avoid handling issues on the road.

Price Range and Budget

I established a budget before diving into my purchase. I found that prices for 100-gallon RV water tanks vary significantly based on material, brand, and features. I compared prices across different retailers to ensure I was getting the best value without compromising quality.

Reviews and Recommendations

Reading reviews from other RV owners helped me understand the pros and cons of various tanks. I sought out forums and discussion boards where people shared their experiences. This firsthand feedback provided valuable insights into the long-term reliability and performance of different tanks.

Final Thoughts

Purchasing a 100-gallon RV water tank is a significant investment, and I wanted to make an informed decision. By considering my needs, the material, size, installation, drainage, weight distribution, and budget, I felt confident that I was ready to make a choice that would enhance my RV experience. I look forward to my future trips with a reliable water supply at hand.
