The most common RV propane tank sizes are the 20 and 30-pound tanks. Smaller RVs may have a single 20-pound tank, while larger RVs may have multiple 30 or 40-pound tanks.
Understanding RV Propane Tanks
RV propane tanks are an essential component of any RV that runs on gas. They come in different sizes and types, depending on the size of the RV and the amount of propane required. In this section, we will discuss the different types of RV propane tanks and their sizes.
Types of RV Propane Tanks
There are two main types of RV propane tanks: DOT cylinders and ASME tanks. DOT cylinders are portable and can be easily removed and refilled. They are commonly used in smaller RVs and camping trailers. ASME tanks, on the other hand, are permanently mounted on the RV and are designed for larger RVs and motorhomes.
RV propane tanks come in different sizes, ranging from 5 pounds to 100 pounds. The most common sizes of RV propane tanks are 20 pounds, 30 pounds, and 40 pounds. The size of the propane tank needed for your RV depends on the size of your RV and the amount of propane you need.
For example, a small travel trailer or truck camper will typically have a single 20-pound DOT cylinder, while a large fifth-wheel camper may carry a series of 40-pound DOT cylinders. This gives the RV a propane capacity of over 100 pounds.
It is important to note that the size of the propane tank does not necessarily indicate the amount of propane it can hold. The capacity of the propane tank depends on the pressure and temperature of the propane.
In conclusion, understanding the different types and sizes of RV propane tanks is essential for any RV owner. It is important to choose the right size and type of propane tank for your RV to ensure that you have enough propane to power all your appliances and equipment.
Size and Weight Considerations
When it comes to RV propane tanks, size and weight are important considerations. In this section, we’ll take a closer look at how size affects weight and how weight affects RV performance.
How Size Affects Weight
The size of your RV propane tank will directly affect its weight. The larger the tank, the more propane it can hold, but also the heavier it will be. The most common sizes for RV propane tanks are 20lb, 30lb, and 40lb. The chart below shows the maximum capacities for each tank size:
| Tank Size | Maximum Capacity |
|---|---|
| 20lb | 4.7 gallons |
| 30lb | 7 gallons |
| 40lb | 9.4 gallons |
It’s important to note that the weight of the tank itself will also need to be factored in. For example, a 20lb propane tank weighs around 18 pounds when empty, while a 40lb tank weighs around 30 pounds when empty.
How Weight Affects RV Performance
The weight of your RV propane tank can have a significant impact on your RV’s performance. The more weight your RV has, the more fuel it will consume, and the harder it will be to maneuver. This is especially true if you have multiple propane tanks or if you have a larger RV.
In addition to affecting fuel consumption and maneuverability, the weight of your propane tank can also impact your RV’s suspension and brakes. If you exceed the weight limit of your RV, you could put undue stress on these components, which could lead to damage and costly repairs.
To ensure that you choose the right size propane tank for your RV, it’s important to consider both the size and weight of the tank. Be sure to also check your RV’s weight limit and consult with a professional if you have any questions or concerns.
ASME Tanks Vs. DOT Cylinders
When it comes to RV propane tanks, there are two main types: ASME tanks and DOT cylinders. Each has its own set of features and benefits, so it’s important to understand the differences between the two.
Features of ASME Tanks
ASME tanks are permanently mounted propane tanks that are typically found on motorhomes. They are designed to be stationary and are built into the motorhome frame. This means that they cannot be removed or switched out like DOT cylinders.
ASME tanks are available in a range of sizes, from 20 to 200 pounds. They are also built to strict safety standards set by the American Society of Mechanical Engineers (ASME).
Features of DOT Cylinders
DOT cylinders, on the other hand, are removable propane tanks that are typically used on travel trailers and fifth wheels. They are smaller than ASME tanks and can be easily removed from the trailer when needed. This makes refilling more convenient.
DOT cylinders are available in a range of sizes, from 7 to 40 pounds. They are also built to strict safety standards set by the Department of Transportation (DOT).
One thing to keep in mind with DOT cylinders is that they require recertification every 12 years from the date of manufacturing, and then every 5 years after that.
Conclusion
In summary, ASME tanks are permanently mounted propane tanks that are typically found on motorhomes, while DOT cylinders are removable propane tanks that are typically used on travel trailers and fifth wheels. Each has its own set of features and benefits, so it’s important to consider your specific needs and usage when choosing between the two.
Propane Consumption in RV Appliances
Propane is a crucial fuel source for many appliances in an RV, including the water heater, furnace, grill, fridge, generator, and stove burners. Understanding how much propane these appliances consume can help you plan your propane usage and avoid running out of fuel unexpectedly.
Propane Consumption in Different Appliances
Different appliances consume propane at different rates. Here’s a breakdown of the average propane consumption per hour for some common RV appliances:
- Water heater: 10,000 BTU/hour
- Furnace: 20,000-40,000 BTU/hour
- Grill: 12,000-20,000 BTU/hour
- Fridge: 1,500-2,000 BTU/hour
- Generator: 5-8 gallons per day
- Stove burners: 6,000-12,000 BTU/hour per burner
How to Calculate Propane Consumption
To calculate how much propane an appliance will consume, you need to know its BTU rating and the amount of time it will be in use. Here’s an example calculation for a water heater that has a BTU rating of 10,000 and will be in use for two hours:
- 10,000 BTU/hour x 2 hours = 20,000 BTUs
- 20,000 BTUs รท 91,600 BTUs per gallon = 0.22 gallons
So, in this example, the water heater would consume approximately 0.22 gallons of propane in two hours of use.
It’s important to note that these are just average consumption rates, and actual consumption can vary depending on factors such as the appliance’s efficiency, the outside temperature, and how often the appliance is used.
Overall, understanding propane consumption in RV appliances can help you plan your propane usage and avoid running out of fuel unexpectedly. By calculating how much propane each appliance will consume, you can better manage your propane supply and ensure that you have enough fuel to last your entire trip.
