Quick Answer
For RVs, an ideal propane tank size is typically between 30-40 gallons, considering the appliance load and travel frequency.
Choosing the Right Propane Tank Size for Your RV
When deciding on the ideal propane tank size for your RV, there are several factors to consider. The type and number of appliances that will be connected to the propane system are crucial in determining the tank size. For example, a propane-powered refrigerator, stove, and water heater will require a larger tank than a simple stove and lantern setup.
Calculating Your Propane Needs
To determine the ideal tank size, calculate your propane usage by considering the BTUs (British Thermal Units) of your appliances. A general rule of thumb is to assume 1-2 pounds of propane per day for a small RV with minimal appliances, and 5-10 pounds per day for a larger RV with multiple appliances. Based on this calculation, a 30-gallon tank can provide 15-30 days of propane supply for a small RV, while a 40-gallon tank can provide 25-60 days of supply for a larger RV.
Tank Size Considerations for Travel and Storage
Another important consideration is the tank size for travel and storage. A larger tank provides more flexibility for extended trips, but may be too heavy or bulky for smaller RVs. For storage, consider the tank size and shape to ensure it fits in the RV’s storage compartment or under the RV. A 30-gallon tank is a good compromise between size, weight, and storage considerations, and can be used for most RV applications, while a 40-gallon tank is better suited for larger RVs with high propane demands.
