Most RVs and travel trailers leave the dealer without the gear you actually need at a campsite. The first time you plug into a miswired pedestal, connect to a high-pressure city water line or dump the tanks, you find out why experienced campers carry a specific kit of essentials. The right accessories protect the RV’s electrical and plumbing systems and make setup faster and less stressful.
This list covers the core gear for new and experienced owners alike: power protection, fresh water, sewer, leveling and stability, tank care and a simple lighting upgrade. Most items are universal across travel trailers, fifth wheels and motorhomes, but the surge protector is sized for 30-amp service, so 50-amp owners should choose the matching version. We lead with the items that prevent expensive damage, then move to convenience.

The 10 best RV and camper accessories in 2026
1. Kohree 30A RV Surge Protector
Best for: Protecting the RV’s electrical system
Campground power pedestals are not always wired correctly, and a voltage spike or reversed polarity can damage an RV’s converter, air conditioner and electronics. Kohree’s 30-amp surge protector plugs in between the pedestal and your shore power cord, absorbing spikes with 12,000 joules of protection.
Built-in indicator lights act as a circuit analyzer, helping you spot common wiring faults before you connect. The housing is IP67 weather-resistant and flame-retardant, with ergonomic grips for plugging and unplugging.
- 30-amp, 12,000-joule surge protection
- Circuit analyzer indicator lights
- IP67 weather-resistant housing
- Ergonomic grip handles
Worth knowing: This is a plug-in surge protector, not a full EMS unit that cuts power during low or high voltage; owners who camp at older parks may want an EMS. 50-amp RVs need a 50-amp model.

2. RVGUARD Water Pressure Regulator with Gauge
Best for: Protecting RV plumbing
City water pressure at some campgrounds can exceed what RV plumbing is designed for, which can burst fittings and cause leaks. RVGUARD’s adjustable regulator attaches at the spigot and has a gauge so you can see the pressure going in.
It’s lead-free brass certified to NSF/ANSI 61 and 372, ships set to 45 PSI and adjusts with a screwdriver. An inlet screen filters debris, and it uses standard 3/4-inch garden hose threads.
- Adjustable, factory-set to 45 PSI
- Built-in pressure gauge
- Lead-free brass, CSA/NSF certified
- Inlet screen filter
Worth knowing: Check your RV manual for its recommended maximum pressure; many owners run between 40 and 60 PSI.

3. Camco RhinoFLEX 20 ft Sewer Hose Kit
Best for: Clean, easy tank dumping
The sewer hose that comes with many RVs is thin and short. Camco’s RhinoFLEX kit includes two 10-foot hoses with pre-attached swivel fittings, a clear elbow so you can see when the tank is empty, a 4-in-1 dump station adapter and storage caps.
The hose uses 23 mils of polyolefin reinforced with steel wire, so it resists punctures and compresses for storage. It’s made in the USA.
- Two 10 ft hoses with swivel fittings
- Clear elbow with 4-in-1 adapter
- Steel-wire-reinforced polyolefin
- Storage caps included
Worth knowing: Store it in a bumper tube or a dedicated bin; a sewer hose should never share storage with your fresh water hose.

4. OULEME 25 ft Drinking Water Hose
Best for: Safe fresh water hookups
Garden hoses can leach chemicals into your water. A drinking water hose is made for potable water, and this 25-foot OULEME hose is lead- and BPA-free with a 5/8-inch inner diameter and an anti-kink design.
It uses aluminum 3/4-inch fittings and is rated for temperatures from -22°F to 158°F and a maximum working pressure of 150 PSI.
- 25 ft, 5/8-inch inner diameter
- Lead- and BPA-free
- Aluminum 3/4-inch fittings
- Rated -22°F to 158°F
Worth knowing: Keep a second hose, in a different color, for flushing tanks so the two never get mixed up.

5. Camco Interlocking Leveling Blocks (10-Pack)
Best for: Leveling on uneven sites
Few campsites are perfectly flat, and an unlevel RV means doors that swing on their own, poor sleep and, in absorption refrigerators, reduced cooling. Camco’s 8.5 x 8.5-inch blocks interlock so you can build a ramp or a stack to the height you need.
They work under single or dual tires, tongue jacks and stabilizer jacks, are made of UV-stabilized resin and are bright yellow so you don’t leave them behind. A storage bag is included.
- 10 interlocking 8.5 x 8.5-inch blocks
- Use under tires, tongue and stabilizer jacks
- UV-stabilized resin
- Bright yellow, with storage bag
Worth knowing: Check the weight limits in the instructions for heavier motorhomes, and always drive onto a full-width stack, not the edge.

6. HOXWELL Heavy-Duty Rubber Wheel Chocks (4-Pack)
Best for: Keeping a trailer from rolling
Before you unhitch a travel trailer or level a motorhome, the wheels need to be chocked. HOXWELL’s solid rubber chocks use a triangular shape with a ribbed, textured base for grip, and they won’t rust or bend like some steel designs.
Each chock measures about 7.9 x 5.9 x 4 inches, and the four-pack lets you chock both sides of a tandem axle. A built-in handle makes them easy to place and retrieve.
- Four solid rubber chocks
- Ribbed, textured base for grip
- About 7.9 x 5.9 x 4 inches each
- Built-in carry handle
Worth knowing: For large fifth wheels and Class A motorhomes, consider bigger chocks or X-style chocks between tandem tires.

7. T-Type RV Levels (4-Pack)
Best for: Quick level checks without a phone
Bubble levels mounted on the RV let you see at a glance which side needs blocks. These T-shaped levels check both directions at once and stick to the front and side of the camper.
They’re inexpensive, don’t need batteries and are visible from the driver’s seat or tongue jack when mounted in the right spots.
- T-shaped, reads two axes
- Set of four
- No batteries or app needed
- Mount on front and sides
Worth knowing: Mount them after you’ve leveled the RV with a carpenter’s level inside, so the bubbles are calibrated to your floor.

8. Unique RV Digest-It Ultra
Best for: Black tank odor and clog prevention
The black tank is the most dreaded part of RV ownership. Unique’s Digest-It Ultra is a concentrated bio-enzymatic liquid that breaks down waste and toilet paper, controls odors and helps prevent buildup that fouls tank sensors.
One bottle provides 32 treatments, and liquid dosing is easy to measure. Unique also offers access to its Colorado-based certified RV technicians through its Unique Cares program.
- Bio-enzymatic formula
- 32 treatments per bottle
- Helps prevent clogs and sensor buildup
- Easy liquid dosing
Worth knowing: Use plenty of water with every flush; no treatment makes up for a dry black tank.

9. Camco TST Grey Water Odor Control
Best for: Kitchen and shower drain odors
Grey tanks collect grease and soap from sinks and showers, and that residue causes odors people often blame on the black tank. Camco’s TST grey water treatment breaks down grease buildup in the tank and drain lines and adds a lemon scent.
It’s septic-safe and formaldehyde-free, and the 64-ounce bottle is concentrated: 4 ounces treats a 40-gallon tank. It’s made in the USA.
- Breaks down grease in tanks and drains
- 4 oz treats a 40-gallon tank
- Septic-safe, formaldehyde-free
- 64 oz bottle, made in USA
Worth knowing: Scrape greasy dishes into the trash before washing; treatments work best alongside good habits.

10. Motion-Activated Rechargeable RV Step Lights
Best for: Safer steps at night
RV entry steps are steep and narrow, and a misstep in the dark is a common campsite injury. These rechargeable lights turn on automatically when they detect motion within about 10 feet, with 44 LEDs producing 200 lumens.
They’re IP67 sealed against rain and dew, charge by USB with a 1,800mAh battery, and offer stepless dimming with three color temperatures.
- 44 LEDs, 200 lumens
- PIR motion sensor, about 10 ft range
- IP67 waterproof
- USB-rechargeable, dimmable, 3 color temps
Worth knowing: You’ll need to recharge them periodically, so hardwired lighting is better if you stay in one place for months.

How to choose RV and camper accessories
Buy the gear that protects your RV’s systems first, then add convenience items as you learn how you camp.
Match your electrical service
RVs use either 30-amp (three-prong) or 50-amp (four-prong) shore power. Surge protectors, extension cords and adapters must match. A basic surge protector absorbs spikes and flags wiring faults; an EMS (electrical management system) also shuts off power during high or low voltage, which protects air conditioners and converters at crowded parks where voltage sags. If you camp often at older campgrounds, an EMS is worth the extra money.
Protect the fresh water system
Always use a white or blue drinking-water-safe hose for fresh water and a pressure regulator at the spigot. Many RV plumbing systems are designed for roughly 40 to 60 PSI, while some city water connections run much higher. An inline water filter is a smart third step. Sanitize the fresh tank and hose at the start of each season.
Get a sewer setup you trust
A good sewer kit has thick hose walls, secure bayonet fittings, a clear elbow to see when the tank is empty, and an adapter for different dump station inlets. Dump the black tank first and the grey tank second so soapy grey water rinses the hose. Wear disposable gloves and keep a dedicated rinse hose separate from your drinking water hose.
Level and stabilize every time
Leveling blocks raise the low side, chocks keep wheels from rolling, and stabilizer jacks reduce bounce, but stabilizers are not designed to lift or level the RV. Check level side to side first, then front to back with the tongue jack or leveling system. A level RV sleeps better, drains correctly and keeps doors and slides working as designed.
Build a kit, not a pile
New owners tend to overbuy. Start with the essentials on this list, take a few trips and note what you actually missed. Keep power gear, water gear and sewer gear in separate labeled bins so setup is quick and nothing cross-contaminates. For towing and highway safety items, see our roadside emergency kit guide.
Frequently asked questions
What accessories do I need for a new RV?
The core list is a surge protector sized to your RV, a water pressure regulator, a drinking-water hose, a sewer hose kit, leveling blocks, wheel chocks and tank treatments. Those protect the electrical and plumbing systems and handle every hookup. Add lighting, organization and outdoor gear once you’ve camped a few times.
Do I really need an RV surge protector?
Yes. Campground pedestals can have wiring faults or voltage spikes, and repairing an RV converter, air conditioner or control board costs far more than a surge protector. At minimum, use one that absorbs surges and shows wiring faults. An EMS unit adds protection against high and low voltage.
What water pressure is safe for an RV?
Many RV plumbing systems are designed for roughly 40 to 60 PSI, but check your owner’s manual for your rig’s recommendation. Use a regulator at the spigot every time you connect to city water, since campground pressure can vary widely and spike without warning.
How often should I treat RV holding tanks?
Add black tank treatment after every dump, along with enough water to cover the tank bottom. Treat the grey tank periodically, especially if you cook and wash dishes in the RV. Flush the black tank regularly to keep sensors accurate and prevent buildup.
How many leveling blocks do I need?
A 10-pack is enough for most travel trailers and small motorhomes, giving you ramps under the tires on one side plus blocks for the tongue jack and stabilizers. Larger rigs and very uneven sites may need a second set. Stack them in a pyramid so the tire rolls up gradually.
The bottom line
Start with the Kohree 30A RV Surge Protector and the RVGUARD water pressure regulator, since they protect the two most expensive systems in any RV. Add the Camco RhinoFLEX sewer kit, a drinking water hose and Camco leveling blocks for easy hookups, and keep Digest-It Ultra on board for the black tank.
