The factory parts on most travel trailers and campers—from the shower head that dribbles to the single-use plastic bins that rattle—are designed to a cost, not to a quality standard. After a few trips, the shower water runs out before the soap does and the cabinets become a chaotic mess of shifting supplies. The difference between a frustrating trip and a comfortable one often comes down to swapping a handful of small, specific components.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I’ve spent years combing through technical specs, user durability reports, and material science data on RV aftermarket components to identify which accessories deliver real, repeatable performance improvements without wasting space or budget.
Whether you are stabilizing the rig on uneven ground or optimizing water usage in the wet bath, the right kit changes the experience. This guide breaks down five purpose-built additions that solve common camper annoyances and highlights the single most important criteria for each category, helping you find the best camper accessories for your next adventure.
How To Choose The Best Camper Accessories
Buying aftermarket parts for a camper is different from outfitting a home. Every ounce of weight and cubic inch of storage space carries a direct penalty in fuel economy or livable room. The guiding principle is to prioritize items that solve a recurring pain point—water conservation, stability, safety, or space optimization—while meeting the physical constraints of the RV environment: vibration, moisture, temperature swings, and road shock.
Water & Waste Management
The most common frustration in a camper wet bath is the factory shower head’s high flow rate combined with low pressure. A standard 2.5 GPM head empties the fresh tank in minutes. Look for heads with a rated flow at or below 1.8 GPM and an integrated pause button. This combination keeps the hot water line primed while you lather up, effectively extending usable shower time without increasing water storage requirements.
Leveling & Stability
Campsites are rarely perfectly flat, and an unleveled trailer stresses the refrigerator cooling system and makes doors swing open. Leveling blocks made of high-density polypropylene with interlocking tabs provide a modular height solution. The key spec to check is the block’s per-square-inch load rating—look for materials that resist cracking under the static weight of the trailer tongue or stabilizer jacks, especially on hot asphalt where softer plastics deform.
Electrical Protection
RV park pedestals are exposed to weather and misuse, often delivering voltage that spikes or fluctuates. A surge protector with a joule rating of at least 10,000 joules and an integrated circuit analyzer is the standard for protecting sensitive electronics like the converter and inverter. The waterproof cover on the plug end is non-negotiable for campers facing rain or dew overnight.

In‑Depth Reviews
1. Awelife RV Shower Head
The water pressure in an RV wet bath is notoriously weak because the pump pulls from a small tank and the factory shower head is usually a low-cost unit that restricts flow without actually increasing spray velocity. The Awelife head addresses this by using a narrower internal orifice design that raises the stream velocity while capping the flow rate at 1.8 GPM, which leaves 28% more water in the tank compared to a standard 2.5 GPM head. The result is a shower that actually rinses suds off before the hot water runs out.
The integrated pause button on the handle shuts the flow off completely at the head rather than allowing the pump to cycle when you are soaping up. This preserves your hot water temperature setting because the line stays full and the heater doesn’t have to re-prime the cold slug. The 60-inch kink-free PVC hose is long enough to reach all corners of a typical wet bath without tangling, and the adhesive-backed bracket lets you mount the holder without drilling into fiberglass walls.
Build quality stands out in the brass swivel fitting and the silicone nozzles that resist hard water scale better than rubber. Users consistently report near-identical pressure to a residential shower once the tank is above half full, and the matte black finish resists water spotting for a clean look. This is the single highest-impact upgrade for any camper with a wet bath.
What works
- Pause button holds temperature without pump cycling
- Noticeably higher stream velocity than factory heads
- Adhesive mount avoids drilling into RV walls
What doesn’t
- Adhesive can fail on textured or dirty surfaces
- Plastic construction may not survive drops on gravel
2. OULEME Leveling Blocks
Single-piece leveling ramps are difficult to position under a trailer tongue that is already low, and they offer no granular height adjustment. The OULEME system uses ten interlocking blocks plus two top blocks, each measuring 8.5 inches square with a 1.5-inch height per block, allowing you to build up exactly the lift needed—anywhere from 1.5 to 15 inches—by snapping pieces together. The polypropylene material is reinforced with UV stabilizers and has higher density than standard plastic ramps, which resists deformation under the weight of a pair of stabilizer jacks.
The blocks have a textured top surface that grips the jack foot or tire tread without sliding, and the interlocking groove pattern runs along two edges so you can create a stable tower rather than a stack of loose squares. The included carrying bag is a thoughtful addition because loose blocks slide around in the cargo hold. Users have noted that the blocks perform reliably under tongue weights up to 1,000 pounds without cracking, and the 0.7-inch top blocks allow fine-tuning when the ground is almost but not quite flat.
The main limitation is that the interlocking tabs are designed for vertical load, not lateral shear—if you back a tire onto them from an angle, the blocks can separate. For straight-in placement under jacks or the stabilizer feet, they are the most space-efficient and customizable solution on the market for the price.
What works
- Customizable height with 1.5-inch increments
- Textured surface prevents jack foot slippage
- UV-resistant polypropylene does not soften in heat
What doesn’t
- Can separate under lateral tire contact
- Bag zipper is lighter-duty than the blocks
3. WECARLLE Wheel Chocks
Plastic wheel chocks can skid on wet grass or gravel because their smooth surfaces lack friction coefficient at the contact patch. The WECARLLE chocks are molded from dense rubber with a Shore hardness that provides enough compliance to grip tire tread patterns without sliding. The 6.21 x 4.71 x 4.31-inch size is large enough to create a positive stop for trailer tires up to a 15-inch diameter, and the angled face is designed to self-tighten as the tire rolls forward against it.
Each chock has three high-reflectivity yellow strips that catch headlight beams from a distance, making them visible in low-light campground conditions or when stowing near the roadside. The 4-pack comes with a connecting rope tether that runs through each pair, so the left and right chocks stay linked and cannot be kicked out of position during setup. The total weight of 5.4 pounds gives each chock enough mass to resist being pushed by the tire without needing to be anchored.
Users consistently rate the rubber compound as superior to cheaper thermoplastic chocks that become brittle in winter temperatures. The rubber also absorbs vibration better than plastic, which reduces the metallic rattle sound when stored. One minor drawback is the weight is noticeable if you carry them in a backpack for a pop-up camper, but for stability under a loaded travel trailer, mass is exactly what you want.
What works
- Rubber compound grips wet surfaces far better than plastic
- Reflective strips improve safety in low light
- Tether system prevents chocks from separating
What doesn’t
- Heavier than plastic alternatives for backpackers
- Rubber can mark sealed concrete or garage floors
4. Sudaya Collapsible Food Storage Containers
Cabinets in a travel trailer are unusually shallow and often wedge-shaped near the ceiling, making rigid rectangular storage containers wasteful of vertical space. The Sudaya set solves this with food-grade silicone bodies that collapse flat when empty, occupying roughly a quarter of the storage volume compared to rigid plastic equivalents. The set includes four size variants: 12 oz, 17 oz, 27 oz, and 40.6 oz, giving you options for everything from leftover coleslaw to a full sandwich kit.
The silicone material is rated from -20°C to 220°C, which means it can go from the freezer to the microwave without cracking or melting. The lids are polypropylene and seal via a four-sided snap closure that is leak-proof when fully engaged—users have reported carrying soup stock without spills. The containers are also dishwasher safe, which is important because hand-washing in an RV sink with limited hot water is tedious. The weight savings alone (roughly 60% lighter than glass or hard plastic equivalents) make a measurable difference over a full camping trip.
The trade-off is that the silicone walls are flexible enough that they can bulge if overfilled, especially the 40.6 oz container when fully loaded with dense food. The lids also require firm, even pressure on all four corners to seal correctly, which takes a bit of muscle the first few uses. For cabinets where every shelf millimeter counts, these containers are the most practical option available.
What works
- Collapses flat when empty to save cabinet space
- Wide temperature tolerance for freezer-to-microwave use
- Leak-proof seal with four-sided snap closure
What doesn’t
- Lids require firm effort to seal completely
- Silicone walls can bulge if overfilled with heavy contents
5. EPLCSE RV Surge Protector 30 Amp
RV park pedestals are often decades old, wired incorrectly by owners, or exposed to weather that causes neutral-ground faults. The EPLCSE surge protector plugs directly between your 30-amp shore power cord and the pedestal, acting as both a circuit analyzer and a surge suppression device. The six diagnostic LEDs on the faceplate indicate normal wiring as well as common faults: reverse polarity, open neutral, open ground, reverse ground-neutral cross, and missing ground. This saves you from plugging in to a pedestal that could fry the converter or start a fire.
The 10,000-joule rating means this unit can absorb multiple large spikes—like from a lightning strike 50 yards away or a nearby AC compressor cycling off—before its protection degrades. The housing is molded from V-1 flame-retardant material, and the plug end has a hinged waterproof cover that seals the connection point against rain and dust. The ergonomic handle on the plug body makes it easy to grip even with cold or wet hands, which is the typical scenario when setting up camp after dark.
FCC certification and RoHS compliance confirm that the internal components meet safety standards for continuous outdoor use. Users appreciate that the LED indicators are bright enough to read in direct sunlight, and the unit is slim enough to fit in tight pedestal enclosures where larger suppressors sometimes can’t plug in. The only real limitation is that this is a 30-amp device, so 50-amp campers will need the alternate version, and the analyzer does not perform a load-test, just a wiring check.
What works
- High joule rating absorbs multiple surge events
- Clear LED diagnostics for six different wiring faults
- Waterproof cover protects connection from rain
What doesn’t
- Only works with 30-amp shore power systems
- No load-testing capability for voltage sag
Hardware & Specs Guide
Flow Rate vs. Tank Capacity
The typical RV fresh water tank holds 30-40 gallons. A standard showerhead at 2.5 GPM drains that in 12-16 minutes. A head rated at 1.8 GPM stretches that to 16-22 minutes, and the pause button adds indefinite stops without losing temperature. For boondockers, this is the difference between a full shower and a sponge bath.
Joule Rating for Surge Suppression
Joules measure the total energy a surge protector can absorb before failing. A standard power strip holds 400-800 joules. RV units should exceed 5,000 joules; the EPLCSE at 10,000 joules handles multiple spikes from generator kicks and grid switching. Once the MOVs inside degrade, the protector will still pass power but no longer clamp surges.
