Must Have Travel Trailer Accessories: Your Complete Setup Guide

Quick Answer: To outfit a travel trailer properly, you need essential accessories for towing, electrical protection, water and sewer management, leveling, power, and daily comfort. The right gear prevents damage, improves safety, and makes setup easier. 

Getting a travel trailer is exciting, but here's something most dealers won't tell you upfront - your trailer doesn't come ready to camp. After talking to full-timers and weekend warriors who've learned these lessons the hard way, we've put together this guide to help you avoid the trial-and-error phase.

Think of these accessories in tiers. Some you absolutely cannot camp without - like a sewer hose and water pressure regulator. Others make life significantly better once you're set up - like proper leveling blocks and surge protection. Then there are the comfort upgrades that transform your trailer from functional to genuinely enjoyable.

Key Takeaways

• A safe setup starts with essential hitch components, brake controllers, mirrors, chocks, and other equipment that supports proper towing and stability.

• Electrical protection matters, including EMS surge protection, heavy-duty power cords, adapters, and battery maintenance tools for reliable 12-volt operation.

• Water and sewer systems require dedicated hoses, regulators, filters, treatments, and cleaning tools to prevent contamination and plumbing issues.

• Comfort upgrades like better storage, outdoor living gear, kitchen tools, and bathroom accessories significantly improve everyday usability.

• Shop high-quality essentials and upgrades through RV Trader Accessories to build a setup tailored to your camping style.

Starting Right: Hook-Up Essentials

Safe towing starts long before you get on the road. A solid setup makes hitching easier, protects your tow vehicle, and keeps your travel trailer stable at highway speeds. The items below help ensure smooth towing, safer braking, and fewer surprises at the campsite.

Trailer Hitch

A trailer hitch is essential because it creates a secure connection between your tow vehicle and travel trailer. It transfers the trailer’s weight safely, keeps the rig stable on the road, and allows you to steer, brake, and control the load without sway or detachment.

Weight Distribution Hitch & Sway Control

A quality weight distribution hitch improves handling by redistributing tongue weight across your tow vehicle’s axles. Models with built-in sway control greatly reduce trailer sway from wind or passing trucks, making highway towing safer and more comfortable.

Hitch Locks and Coupler Locks

These keep your trailer secure both on and off the tow vehicle. A locking hitch pin prevents theft while towing, and a coupler lock protects the trailer when unhitched at home or a campground.

Brake Controller (If Not Integrated)

Many trailers require a brake controller by law. It synchronizes your truck and trailer brakes, giving you smoother, safer stops and reducing wear on your tow vehicle.

Extended Tow Mirrors

Snap-on or replacement mirrors give you the visibility needed to see down both sides of the trailer. They’re essential for lane changes, backing up, and tight campground navigation.

Trailer Wiring Tester

A simple plug-in tester lets you confirm brake lights, turn signals, and running lights before you start driving. It’s a quick, reliable way to catch wiring issues early.

Emergency Breakaway Cable

Required on most trailers, this cable activates the trailer brakes if it becomes disconnected from the tow vehicle. Inspect it regularly and replace it if frayed.

A Note on Trailer Weight & Loading

A quick weigh-in at a public scale on your first trip helps confirm you're within safe limits. Aim for a tongue weight of about 10%-15% of the trailer’s total weight for best stability.

Browse quality RV trailer hitches and tow & haul accessories to get your towing setup right from the start.

Electrical Protection

Your travel trailer’s electrical system powers everything from heat and air conditioning to refrigerators, lights, and device charging. Protecting that system - and keeping power flowing smoothly - is one of the most important parts of RV ownership. The items below help prevent damage, ensure safe connections, and keep you powered anywhere you camp.

Surge Protector or EMS (Electrical Management System)

A must-have for every RV. A basic surge protector shields your trailer from power spikes, but an EMS provides full protection by also monitoring for low voltage, high voltage, reverse polarity, open grounds, and miswired pedestals. Consider this an insurance policy for your trailer’s electrical system.

30A or 50A Shore Power Cord

Use the correct cord for your trailer’s electrical service. Look for a heavy-duty, weather-resistant cord with molded ends and built-in grip handles for safer plugging and unplugging.

Voltage Tester (Non-Contact or Plug-In)

A quick test at the pedestal before plugging in can prevent serious damage. Always verify proper wiring, polarity, and grounding.

Battery Tender or Smart Charger

When your trailer is stored, a smart charger maintains your battery at optimal levels without overcharging. This extends battery life and prevents deep discharge damage.

12V Fuses and Spare Breakers

Always carry replacements for the fuse sizes your trailer uses (commonly ATC/ATO fuses). A popped fuse is one of the most common causes of dead lights or non-working appliances.

USB/12V Charging Hub

A multi-port hub makes it easier to charge phones, tablets, cameras, and GPS devices without overloading outlets inside the trailer.

Check out power protection options designed specifically for RV electrical systems.

Fresh Water System

Your travel trailer’s water system is one of the most important parts of comfortable camping. From safe drinking water to proper waste management, the right tools help prevent leaks, contamination, clogs, and costly repairs. This section covers everything you should carry for hookups, sanitation, and routine maintenance.

Fresh Water Hose (Drinking Water Safe)

Choose a dedicated potable water hose - usually white or blue - specifically rated for drinking water. Avoid using standard garden hoses, which can leach chemicals and affect taste.

Water Pressure Regulator (Adjustable Preferred)

Campground water pressure is notoriously unpredictable. A regulator protects your trailer’s plumbing from high pressure that can rupture lines or damage fittings. Adjustable models with gauges let you fine-tune pressure for your system.

Inline RV Water Filter or Canister Filtration System

Filters remove sediment, bad taste, chlorine, and contaminants before water enters your trailer. Basic inline filters are convenient, while canister systems provide higher-quality filtration.

Brass Hose Splitter (Y-Valve)

Allows you to run two hoses at once - one for the trailer, one for rinsing gear or flushing tanks. Choose heavy-duty brass to prevent leaks.

Hose Quick-Connect Fittings

Quick-connects make setup fast and reduce wear on hose threads. Use them on your spigot, pressure regulator, and hose ends.

Heated Water Hose (For Cold-Weather Camping)

Prevents water lines from freezing, making it essential for winter RVing or shoulder-season trips.

Clear Sewer Elbow (90° Fitting)

A clear elbow lets you monitor tank flow when dumping. It helps identify clogs, confirms when tanks are clean, and prevents over-flushing.

Sewer Hose (Heavy Duty)

A quality hose with wire reinforcement and leak-proof fittings is non-negotiable. Longer hoses (20-30 ft) provide extra flexibility at awkward dump stations.

Black Tank Treatment (Drop-in Pods or Liquids)

Breaks down solids, controls odor, and supports tank health. Enzyme-based options work well and are septic-safe.

Portable Waste Tote (Optional, for No-Sewer Campsites)

Ideal for extended stays at sites without sewer hookups. Allows you to transport grey/black water to a dump station without moving your entire trailer.

Small Plumbing Tool Kit

• Pliers

• Adjustable wrench

• Replacement PEX clips or crimp rings

• Utility knife

• Rubber gloves

This helps you handle minor leaks or quick repairs on the road.

Getting Level and Stable

A stable, level trailer protects your frame, improves appliance performance, and makes everyday tasks far more comfortable. These essentials help you set up quickly and keep your RV solid and wobble-free once parked.

Wheel Chocks (Rubber or Heavy-Duty Plastic)

The first step before leveling. Chocks prevent any rolling during setup. Rubber offers the best grip on gravel and wet surfaces.

X-Chocks (Wheel Stabilizers for Dual Axle Trailers)

These expand between the tires to lock them in place, dramatically reducing front-to-back movement when walking inside.

Leveling Blocks

Interlocking blocks or wooden ramps help you correct side-to-side unevenness. Build up the required height and drive onto them for a level foundation.

Bubble Levels or Digital Level Indicators

Mount small bubble levels on the exterior or use a digital leveling device for perfect alignment front-to-back and side-to-side.

Tongue Jack (Manual or Electric)

Used only for front-to-back leveling (not towing). An electric jack makes the process faster and more accurate.

Stabilizer Jacks (Scissor or Electric)

Once the trailer is level, stabilizer jacks prevent movement when walking around inside. These are not for lifting - only for eliminating shake.

Stabilizer Jack Pads

Placed under stabilizer feet to stop sinking and reduce vibration. Also protect paved campground pads from metal scuffing.

Stackable Stabilizers or Stack Jacks

Useful for older trailers or units with weaker stabilizers. Provide extra support under slide-outs or soft floor areas.

Wheel Leveling Ramps for Single-Axle Trailers

Safer and faster than using blocks when your site is significantly uneven on one side.

Anti-Vibration Pads

Placed under stabilizers or jacks to reduce interior shaking, especially on gravel or rocky sites.

Manual Crank & Drill Adapter

If your stabilizers use a manual crank, having a drill adapter lets you raise or lower them in seconds.

Ground Protection Mats

Placed under your leveling area to keep your campsite tidy, prevent sinking, and make adjustments easier in muddy or sandy conditions.

Find jacks, leveling, and chocks to get your trailer perfectly positioned at every site.

Power and Connectivity

A dependable power setup keeps your trailer’s lights, appliances, and 12-volt systems running smoothly - especially when you're away from shore power. These essentials help maintain your batteries, protect your electrical system, and keep you connected wherever you camp.

Battery Maintenance Tools

Your 12-volt system depends on healthy batteries. Keep:

• Distilled water for non-sealed batteries

• A simple voltmeter or multimeter for checking charge levels

These basics extend battery life and prevent unexpected failures.

Portable Solar Panel Kit or Roof-Mounted Solar

Solar keeps your batteries charged during off-grid stays. Portable panels are flexible for short trips, while roof-mounted arrays offer continuous charging.

Generator or Portable Power Station

A 2000-3000W inverter generator (or a quiet power station) provides backup power for boondocking, running small appliances, or recharging batteries on cloudy days.

Cell Signal Booster or WiFi System

Reliable internet in remote areas requires a booster (like WeBoost) or a dedicated RV WiFi setup. Perfect for work, streaming, or navigation.

Two-Way Radios for Backup Communication

Useful when spotting during tricky backing maneuvers - especially in locations with poor cell service.

Browse portable power stations to extend your off-grid capabilities.

Kitchen Storage and Organization

Travel trailer kitchens are exercises in efficient space use.

• Collapsible kitchenware (bowls, colanders, dish racks)

• Instant Pot or multi-cooker

• Clear storage bins with tall sides for cabinets, fridge, and pantry

• Magnetic spice racks

• Adhesive paper towel holders

Everything shifts during travel, and bins keep items corralled while maximizing vertical space.

Bedroom Comfort

RV mattresses are often shorter and narrower than residential beds, requiring specialized bedding.

Bedroom essentials:

• RV-specific sheets (short queen 60" x 75" is most common) with deep pockets

• Quality mattress topper for thin factory mattresses

• Cooling sheets or moisture-wicking bedding

• Small USB-powered fan for airflow

• Over-the-door organizers for closet storage

• Under-bed storage bags with clear windows

Building Your Accessory List

Start with the absolute essentials - the safety equipment, hook-up items, and basic leveling tools. You can camp without most comfort items, but you can't legally tow without proper safety chains, and you'll damage your plumbing without water pressure regulation.

Priority ordering:

1. Safety and Hook-Ups First: Towing equipment, electrical protection, water system, sewer setup

2. Stability and Comfort Basics: Leveling blocks, stabilizer jack pads, battery maintenance

3. Personalized Upgrades: Build out based on your camping style (boondocking vs. full hookups, weekend trips vs. full-time)

Keep a running list in your phone of items you wish you had during each trip. By your third or fourth outing, you'll have a solid understanding of what upgrades actually matter for your camping style versus what just looks appealing in catalogs.

One more piece of advice from experienced RVers - resist buying every accessory upfront. Let your actual camping experiences guide your purchases. You'll spend less money on things that end up collecting dust in a storage bay, and more on the items that genuinely improve your time on the road.
