Thinking of leaving your RV plugged in 24/7? It’s a common question, and there are some good reasons to keep it powered up – but a few important drawbacks, too. Let’s take a look at the pros and cons so you can decide what works best for your setup.
Why Keep Your RV Plugged In?
There are a few reasons you might want to stay plugged in:
Living Full-Time in Your RV: If your RV is your home, staying connected to power makes sense.
Keeping the Fridge Running: Want a cold fridge ready for a quick weekend getaway? Staying plugged in can help.
Keeping Batteries Charged: It’s convenient to have fully charged batteries for those impromptu boondocking trips.
Preventing Freezing Pipes: Running the heat in colder months can help protect pipes during those in-between trips.
Does Staying Plugged In Damage RV Batteries?
Battery life is one of the top concerns when it comes to constant charging. The answer here depends on your RV’s setup:
Newer RVs: Most modern rigs come with a “smart” charger that prevents overcharging by switching to a slow trickle charge once batteries are full. If your RV has one of these, you’re likely safe to stay plugged in as long as you periodically check the fluid levels.
Older RVs: Older models usually lack smart charging, which can lead to overcharging and battery damage if left plugged in continuously. Consider upgrading your converter or unplugging the RV between trips to keep your batteries in good shape.
Other Drawbacks of Staying Plugged In
If battery damage isn’t a worry, there are still a few other potential downsides:
Cost: Staying plugged in adds to your electric bill, especially if you’re running appliances like the fridge or heater.
Wear and Tear: RV appliances aren’t designed for 24/7 use. Running them constantly can cause them to wear out faster.
Cold Weather Damage: Cold weather can reduce battery health, even if they’re plugged in. Consider removing and storing your batteries in a warmer place if your RV will be sitting in freezing temps.
Fire Risk: Electrical fires are rare, but a risk nonetheless. If a fire started while you’re away, it could result in major damage.
Alternatives to Staying Plugged In
If you’d rather avoid some of these issues, here are a few alternatives to help you stay camping-ready without needing a constant power connection:
Battery Maintenance: Take your batteries out, top off the fluids, and keep them in a warm spot on a trickle charger. They’ll stay charged and ready for your next adventure.
Quick Fridge Cool-Down: You don’t need to keep the fridge running the whole time. Plug in your RV a day before your trip, then load the fridge with frozen water bottles to speed up cooling.
Winterize Your RV: Instead of running your heater all winter, winterize your RV’s water system to prevent freezing. You can always de-winterize for quick trips and winterize again if you’re traveling in colder months.
So, Should You Keep Your RV Plugged In?
If you’re living in your RV full-time, staying plugged in makes sense. But if your RV is just in storage, leaving it plugged in might not be the best idea. With a little prep work, you can protect your RV – and your wallet – without the need for constant power.
