7 Best Accessories for RV (Researched and Compared)

After researching and comparing dozens of RV accessories based on manufacturer specifications, published safety standards, and aggregated owner feedback, we have selected seven products that address common pain points for RV owners. Our evaluation focuses on real-world performance, durability, and value, with honest notes on limitations and who should skip each pick.

1. TireMinder TM55C Tire Pressure Monitoring System: Best Overall Tire Monitor

🛒  Check Price on Amazon →

The TireMinder TM55C is a well-regarded TPMS that provides real-time pressure and temperature data for up to 6 tires. In our evaluation based on owner feedback and the spec sheets, it offers reliable alerts for slow leaks and rapid pressure drops, which is critical for safety. The flow-through sensors are a thoughtful touch, allowing you to add air without removing the sensor. However, the sensor bodies are somewhat bulky and may be prone to scraping on low-profile wheels or tight curb situations.

This system is ideal for RVers who want comprehensive monitoring and don’t mind the larger sensor profile. If you have very tight wheel clearance or prefer a more compact design, consider the EEZTire system instead.

• Monitors tire pressure and temperature in real time
• Flow-through sensors allow easy inflation without removal
• Repeater extends range up to 60 feet for towable RVs

Pros: Accurate and responsive alerts; Easy to install and pair sensors
Cons: Sensors are large and may hit curb on some wheels

2. Camco 44525 TastePURE Water Filter with Flexible Hose: Best Value Water Filter

🛒  Check Price on Amazon →

The Camco TastePURE filter is a popular entry-level solution for improving RV water quality. Based on owner feedback, it effectively reduces chlorine taste and sediment down to 20 microns. The included hose is a nice bonus, though it is not as durable as a dedicated drinking water hose. In our evaluation, the filter works well for typical campground water but may clog quickly if you encounter very dirty water.

If you need higher filtration for well water or want a longer-lasting filter, consider a larger canister system like the iSpring. This Camco is best for casual RVers who want an affordable, no-fuss upgrade.

• Reduces bad taste, odor, chlorine, and sediment
• Includes a flexible 5-foot drinking water hose
• Easy inline connection between city water and RV

Pros: Affordable and effective for basic filtration; Hose included saves extra purchase
Cons: Not suitable for heavy sediment or high flow rates

3. Valterra 12V Blade-Out Valve for RV Sewer: Best Sewer Valve Upgrade

🛒  Check Price on Amazon →

The Valterra 12V Blade-Out Valve is a solid choice for RVers who want to upgrade from manual sewer valves. In our research, the stainless steel blade and motorized actuator provide reliable sealing and easy operation. However, installation is not for the faint of heart; you must cut your RV’s sewer pipe and wire the valve to a 12V source. Some owners report that the valve can be sluggish in freezing temperatures.

This product is best for DIY-oriented RV owners who want convenience and are comfortable with moderate electrical work. If you prefer a simpler solution, stick with a manual valve or a cable-operated system.

• Electric actuation eliminates manual twisting
• Corrosion-resistant stainless steel blade
• Includes wiring harness and mounting hardware

Pros: Convenient remote operation from inside the RV; Sturdy construction
Cons: Installation requires cutting into existing sewer pipe; Motor can be slow in cold weather

4. Andersen Hitches 3604 Leveling Blocks (10-Pack): Best Lightweight Leveling Blocks

🛒  Check Price on Amazon →

Andersen’s leveling blocks are a favorite among RVers for their low weight and compact storage. In our evaluation, the interlocking design allows you to build up to 3.5 inches of lift, and the blocks grip well on gravel and pavement. Based on owner feedback, they hold up well for typical travel trailers and motorhomes. However, some users with heavy fifth wheels have reported slight flexing under extreme loads.

These are ideal for RVers who prioritize weight savings and ease of use. If you have a very heavy rig or need a more robust solution, consider the heavier-duty Lynx Levelers.

• Each block supports up to 10,000 lbs per pair
• Snap-together design for custom height
• Made from UV-stabilized polypropylene

Pros: Extremely lightweight and easy to store; Non-slip surface works well on most terrain
Cons: Can flex under very heavy loads (over 30,000 lbs); Not as durable as solid wood or plastic ramps

5. Surge Guard 44270 Portable Surge Protector: Best Portable Surge Protector

🛒  Check Price on Amazon →

The Surge Guard 44270 is a top-rated portable surge protector that provides robust protection for your RV’s electrical system. In our research, it meets UL standards and offers real-time monitoring of voltage and current. The weather-resistant design is a plus for outdoor use. However, its size and weight can make it awkward to handle, especially when plugging into a pedestal. Some owners also note the LCD screen is not very bright outdoors.

This is an excellent choice for RVers who want maximum protection and don’t mind the bulk. For a more compact option, consider the Progressive Industries EMS-PT30X.

• Protects RV electrical system from surges and spikes
• Digital display shows voltage, current, and error codes
• Weather-resistant housing with locking cover

Pros: Comprehensive electrical protection; Easy to read status display
Cons: Bulky and heavy compared to inline models; Display can be hard to read in direct sunlight

6. Camco 40043 Adjustable RV Vent Cover (White): Best Budget Vent Cover

🛒  Check Price on Amazon →

The Camco 40043 is a basic vent cover that lets you keep your roof vent open during light rain. In our evaluation, it is easy to install and fits most standard vents. However, the ABS plastic is not the most durable; several owners report cracking after a few years of UV exposure. The adjustable height is handy but the mechanism feels a bit flimsy.

This cover is best for budget-conscious RVers or those who only need occasional rain protection. If you want a more durable and aerodynamic design, the MaxxAir II is a better investment.

• Allows vent use even in light rain
• Adjustable from 1.5 to 4.5 inches height
• UV-resistant ABS plastic construction

Pros: Very affordable; Easy to install with included hardware
Cons: Plastic can become brittle over time in hot sun; Not as aerodynamic as low-profile covers

7. RV Designer E451 Sewer Hose Kit (15 ft): Best Basic Sewer Hose Kit

🛒  Check Price on Amazon →

The RV Designer E451 is an entry-level sewer hose kit that covers the basics. Based on owner feedback, it works for occasional use but the hose is relatively thin and can develop kinks that restrict flow. The fittings are functional but some users report leaks at the connection points if not seated well. The storage cap is a nice touch but not airtight.

This kit is suitable for new RVers on a tight budget or as a spare. For regular use, we recommend upgrading to a thicker hose like the Camco RhinoFLEX.

• 15-foot pre-attached hose with bayonet fittings
• Includes 4-in-1 adapter for various dump stations
• Storage cap with hose retainer

Pros: Complete kit ready to use out of box; Adapters fit most connections
Cons: Hose is thin and prone to kinking; Fittings may leak if not tightened properly

Frequently Asked Questions

What is the most important RV accessory for safety?

A tire pressure monitoring system (TPMS) is often considered the most critical safety accessory. Tire blowouts are a leading cause of RV accidents, and a TPMS alerts you to pressure or temperature changes before a failure occurs. The TireMinder TM55C is a top choice based on our research.

Do I need a surge protector for my RV?

Yes, a surge protector is highly recommended to protect your RV’s electronics from power surges and faulty campground pedestals. The Surge Guard 44270 provides both surge protection and voltage monitoring, helping you avoid damage from high or low voltage conditions.

How do I choose the right leveling blocks?

Consider the weight of your RV and the terrain you encounter. Lightweight interlocking blocks like the Andersen 3604 are great for travel trailers and motorhomes under 30,000 lbs. For heavier rigs, look for heavier-duty blocks such as the Lynx Levelers. Also ensure the blocks provide enough lift range for your needs.

Can I use a standard water hose for my RV?

No, you should use a dedicated RV drinking water hose that is lead-free and rated for potable water. A filter like the Camco TastePURE can further improve taste and reduce sediment. Standard garden hoses can leach chemicals and are not safe for drinking water.

How often should I replace my sewer hose?

Replace your sewer hose when you notice cracks, leaks, or stiffness. For occasional use, a basic kit like the RV Designer E451 may last a season or two. For frequent use, invest in a thicker hose like Camco RhinoFLEX which can last several years with proper care.
