When you’re on the hunt for RV propane tanks for your motorhome, two major industry leaders come to mind: Manchester Tank and Flame King. However, there are other reputable brands offering high-quality products for RV enthusiasts. In this article, we’ll recommend five top products from these manufacturers and others, complete with specifications, purchasing options, and suggested accessories to complement your setup.

Understanding ASME and DOT Standards

Before diving into the product recommendations, it’s important to understand the two main types of propane tanks: ASME and DOT.

ASME (American Society of Mechanical Engineers) Tanks:

• No certification required after purchase.
• Constructed from thicker steel, making them heavier but more durable.
• Designed for permanent installation and stationary use.
• Built according to strict standards set by the American Society of Mechanical Engineers.

DOT (Department of Transportation) Tanks:

• Must be re-certified 12 years after production, then every 5 years.
• Made for portable use and governed by DOT regulations.

Important Note: Motorhomes should always use ASME propane tanks due to their durability and stationary design.
