Features to Consider When Purchasing Best RV LP Regulator

1. Types of RV Propane Regulator

Single Stage Regulators

To be honest, the single-stage regulator is not usable with RVs. It is more suitable for smaller applications that you can use outside your RV. 

For example, you can use a single-stage regulator for a portable campfire or a barbecue grill. If you try to use it with your RV, the outcome will be highly damaging as the pressure will turn up at erratic levels.

Two-Stage Regulators

Almost all RVs have two-stage regulators. They can handle all the necessary propane you have onboard your RV, such as water heaters, ovens, furnaces, or stoves. For larger RVs, you can use high flow two-stage regulators as well. 

For instance, if your RV is 40ft class A, it is more appropriate for you to choose a high flow two-stage regulator model. Plus, these products also handle multiple furnaces, outside kitchens, or accessory connections for portable grills or campfires.

Automatic Dual Tank Regulator

The automatic dual tank regulator will be appropriate for an RV having multiple propane tanks. Thanks to the lever on the regulator, the propane source is provided continuously to the RV owner.

2. Build Quality

The high build quality plays a critical role in the propane system of your RV. So, you should scrutinize the material or the model before buying it. Typically, the best model has a lifespan of 15 years, which means that you have to find another model coming close to the previous one. 

Keep in mind that your evaluation will determine how long you can use it. In most cases, the materials often are brass, stainless steel, aluminum, or raw zinc. These constructions are relatively durable. However, you still should read customer reviews to grab more information.

3. Capacity

Each of the RV propane regulators will have different capacities of BTU. This aspect measures the gas amount permitted to flow into the appliances. As you may know, the higher the BTUs are, the more gas the propane regulator can let out. 

But when the BTUs are higher, the price is also higher. So, you need to find out the number of BTUs which satisfy your propane needs.

4. Covers

The cover will keep the RV propane regulator from corrosion or rust. However, some manufacturers do not include the covers in the regulator purchase. It will be a hassle for customers as they need to research the cover separately.

Accordingly, you should purchase an RV propane regulator coming with a cover.
