RV Surge Protector vs. Leveling Blocks: Which to Buy First?

Product Overview: The Contenders

Progressive Industries EMS-PT30X: Your RV’s Electrical Bodyguard

The Progressive Industries EMS-PT30X Portable RV Surge Protector represents the gold standard in RV electrical protection. Priced at $159.99 with an impressive 4.8-star rating from 3,567 reviewers, this 30-amp portable unit does far more than just guard against lightning strikes. According to thousands of satisfied RVers, this device has saved them from costly electrical damage by detecting faulty campground wiring before it can harm their rigs.

What sets this surge protector apart is its comprehensive monitoring system. The built-in LCD display shows real-time error codes, alerting you to problems like open ground, reverse polarity, low or high voltage, and open neutral conditions. The automatic shutoff feature immediately disconnects power when dangerous conditions are detected, giving campers peace of mind whether they’re inside the RV or away exploring. Reviewers consistently note that the all-weather protection housing holds up beautifully through rain, snow, and intense sun exposure.

Camco 44543 Leveling Blocks: The Foundation of Comfort

The Camco 44543 Leveling Blocks might seem like simple plastic blocks, but they’re one of those accessories that immediately improves your camping experience. At $39.99 with a stellar 4.7-star rating from an impressive 12,456 reviews, this 10-pack of interlocking leveling blocks has become a staple in RV storage compartments across North America.

Each block measures 8.5 x 8.5 x 1.5 inches and can support up to 40,000 pounds, making them suitable for everything from small travel trailers to large motorhomes. The interlocking design allows you to create custom heights in 1.5-inch increments, and campers love how the system stays locked together as you drive onto them. The included carrying bag keeps everything organized, and reviewers frequently mention how the bright yellow color makes them easy to spot when packing up camp.

Side-by-Side Feature Comparison

Use-Case Scenarios: Who Wins?

For Budget-Conscious Buyers

Winner: Camco 44543 Leveling Blocks

At $39.99, the leveling blocks represent the more affordable entry point. For RVers just starting out or those watching every dollar, these blocks deliver immediate, noticeable improvements to camping comfort. You’ll sleep better, your refrigerator will run more efficiently, and you’ll reduce wear on your RV’s frame and systems. While electrical protection is crucial, if your budget only allows for one purchase right now, leveling blocks give you tangible benefits at every campsite. Many experienced campers suggest buying the blocks first, then saving up for the surge protector over the next few months.

For Serious Full-Time RVers

Winner: Progressive Industries EMS-PT30X

If you’re living in your RV full-time or spending extended periods on the road, the surge protector becomes non-negotiable. Reviewers who RV full-time consistently emphasize that this device has saved them from dangerous electrical situations at sketchy campgrounds. The LCD display educates you about power quality at each site, and the automatic shutoff has protected countless rigs from damaging voltage spikes and faulty pedestals. One electrical repair can easily cost $1,000 or more, making the $159.99 investment seem modest in comparison. Full-timers should consider both products essential, but if choosing only one initially, electrical protection guards your home on wheels.

For Weekend Warriors and Occasional Campers

Winner: Camco 44543 Leveling Blocks

If you’re camping just a few times per year at established campgrounds with well-maintained electrical systems, leveling blocks deliver more immediate quality-of-life improvements. Weekend campers report that being level makes a huge difference for sleeping, cooking, and just feeling comfortable in the RV. While surge protection is still important, occasional users at reputable RV parks face lower electrical risk than full-timers bouncing between random campsites. Start with the blocks and consider adding the surge protector as your camping frequency increases.

For Owners of Expensive, Modern RVs

Winner: Progressive Industries EMS-PT30X

Modern RVs come packed with expensive electronics, sophisticated control systems, and sensitive appliances. If you’ve invested $50,000 or more in your rig, spending $159.99 on electrical protection is simply smart risk management. Reviewers with newer RVs emphasize that today’s computerized systems are particularly vulnerable to power quality issues. One voltage spike can fry multiple circuit boards, and replacement parts for modern RVs often require expensive dealer service. The Progressive Industries EMS-PT30X acts as an insurance policy for your significant investment.

For Family Campers with Kids

Winner: Camco 44543 Leveling Blocks

Families camping with children particularly appreciate being level. Kids are more comfortable sleeping, there’s less spilled juice at breakfast, and parents report that even slight slopes can make a cramped RV feel more chaotic. The leveling blocks create a stable, level platform that makes family life in an RV much more pleasant. While electrical safety matters for families too, the immediate comfort benefits of leveling make these blocks the priority purchase for family camping trips. Plus, at half the price, they leave budget for other family camping gear like the Camco 40-Foot TastePURE Drinking Water Hose or the Valterra Adjustable Water Regulator.

For Tech-Savvy Campers Who Love Data

Winner: Progressive Industries EMS-PT30X

If you’re the type who loves monitoring and understanding your RV systems, the Progressive surge protector delivers fascinating real-time data. The LCD display shows voltage readings and error codes that educate you about power quality at different campgrounds. Tech-oriented campers love diagnosing electrical issues before they become problems and appreciate having concrete data about campground electrical systems. Reviewers mention that the device has helped them make informed decisions about whether to stay at questionable campgrounds or move to facilities with better power infrastructure.

Additional Considerations

Installation and Ease of Use

The Progressive Industries EMS-PT30X couldn’t be simpler: plug it into the campground pedestal, then plug your RV cord into the surge protector. The LCD display immediately shows the status, and you’re protected. No tools, no installation, no learning curve. Campers appreciate that it’s truly plug-and-play.

The Camco 44543 Leveling Blocks require a bit more work but remain straightforward. You’ll stack the blocks to the needed height, drive onto them, and then check your level to ensure proper positioning. First-timers typically need a couple of attempts to get it right, but reviewers note that you quickly develop a feel for it. Having a second person to guide you makes the process even easier.

Durability and Longevity

Both products earn high marks for durability. The surge protector’s all-weather housing protects the internal electronics from the elements, and reviewers report years of reliable service. The leveling blocks are made from tough, UV-stabilized plastic that holds up to the weight of heavy RVs and the punishment of repeated use. Multiple reviewers mention using their Camco blocks for five or more years without issues.

Storage and Portability

The surge protector wins on compactness—it’s roughly the size of a hardcover book and weighs about three pounds. The leveling blocks come in a carrying bag but take up more space, roughly equivalent to a large gym bag. Neither presents serious storage challenges for most RVs, but if you’re extremely tight on space, the surge protector has the smaller footprint.

Pro Tips from the RV Community

• Start a Priority List: Most experienced campers suggest building your accessory collection systematically. Consider getting the Camco 44543 Leveling Blocks first, then saving for the surge protector. Add other essentials like the Valterra Water Regulator ($12.99) and Camco RhinoFLEX Sewer Hose Kit ($39.97) as budget allows.
• Consider Your Camping Style: Boondockers and free campers should prioritize the surge protector since they’re more likely to encounter questionable power sources. Campground regulars can start with leveling blocks.
• Read the Manual: The Progressive surge protector’s manual explains all the error codes. Take time to understand what they mean—it’s valuable education about RV electrical systems.
• Practice at Home: Before your first trip, practice using your leveling blocks in your driveway. You’ll arrive at campgrounds more confident and set up faster.
• Check Compatibility: The EMS-PT30X is designed for 30-amp service. If you have a 50-amp RV, you’ll need the 50-amp version. The leveling blocks work with any RV size within the 40,000-pound capacity.

The Verdict: Which Should You Buy?

Here’s the honest truth: eventually, you’ll want both of these products. They address completely different needs, and both are considered essential by the RV community for good reason. But if you’re choosing just one right now, here’s our guidance:

Buy the Camco 44543 Leveling Blocks first if: You’re budget-conscious, camp occasionally at established campgrounds, prioritize immediate comfort improvements, or are just getting started with RVing. At $39.99, they deliver tremendous value and you’ll use them at nearly every campsite.

Buy the Progressive Industries EMS-PT30X first if: You’re a full-timer, own an expensive modern RV, frequently camp at older or unknown campgrounds, or want the peace of mind that comes with comprehensive electrical protection. The $159.99 investment can prevent thousands in repair costs.

The beauty of both these products is their stellar reputation among the RV community. With thousands of five-star reviews between them, you can’t go wrong with either purchase. They represent the kind of well-designed, reliable gear that makes RV camping more enjoyable and worry-free.
