9 Best Travel Trailer Accessories: Our Must-Have Gear

Before setting out on your next adventure, it’s important to make sure you’re well equipped.

You can never be too prepared when it comes to RVing, so we’ve gathered a list of our top travel trailer accessories to help you equip yourself for the trails to come. 

We’ve organized the list below based on a few major categories, including:

• The essentials (or things that are really useful)
• Emergency accessories
• And accessories related to your electric, water, and sewer systems

Some of these accessories are invaluable, others are just really handy and nice to have, but all are incredibly useful. 

Let’s take a look! 

9 Best Travel Trailer Accessories

Below, you’ll find our favorite travel trailer accessories for a variety of purposes.

Each has some unique use in your RV travels, from storage to easier stabilizing when you pull into camp to a variety of other purposes.

Let’s start with some accessories that help with the essentials:

Essential Travel Trailer Accessories

First, let’s talk about some essentials you should do without:

1. Leveling blocks

When it comes to leveling their trailer, everyone seems to swear by something different. However, one of the more popular levelers that’s become popular recently are the Andersen Hitches leveling blocks. 

They have a distinct curved red appearance and many reviewers report that they work like a charm.

Whether you use custom leveling blocks like these, concrete blocks, wood, or something else, having a dependable set of leveling blocks for when you pull into camp is essential.

2. Leveling device

Another essential is some sort of leveling tool. Many trailers now come standard with levels built into the front, back, and sides of the trailer, but yours may not.

If not, you can get something similar to stick onto all four points with a simple adhesive, like these from Sun Company:

A carpenter’s level is another option, and one you might want anyway. It’s a more traditional leveling tool and one you’ve likely seen before:

Either way, once you get your leveling tool, learn more about where to place the level on a travel trailer for a full guide on how to use it.

3. Cell signal booster

A cell signal booster is an incredibly useful tool for improving the power and quality of your smartphone’s cell signal. 

With a cell signal booster, you’re able to reach cell towers that are further away, giving you service further than normal and making your service overall more reliable.

Emergency & Safety Accessories

Next, here are some must-have accessories related to safety and emergency preparedness: 

4. WiFi temperature monitor

A temperature monitor is useful for a number of reasons, but especially important if you have furry companions with you on the road.

Death by overheating is a very real danger for pets and many die each year due to it. 

With a temperature and humidity monitor like the ones we review in our guide on the best RV pet monitors, you can set up automatic alerts to notify you when your RV’s temperature has gone too high if and when you ever need to step away.

5. Surge protector

A surge protector is a valuable tool on the road, most importantly due to the fact that you’ll occasionally run into faulty electrical pedestals at campsites.

If that happens and you’re not using a surge protector, you could be looking at major damage to your entire electrical system.

With something as simple as this Watch Dog 30 Amp EPO surge protector, it protects you in the event of a faulty pedestal so you never have to worry. 

Plus, they’re inexpensive, so they’re one of those must-haves that you have no excuse not to carry on the road. 

Learn more about why we recommend an EPO over a typical surge protector.

6. Water sensor

A water sensor, like the Govee WiFi water sensor above, allows you to detect moisture automatically throughout RV where it shouldn’t be.

Water leaks are the bane of every long-time RVer, with the potential damage of a single leak potentially leading to thousands in repairs and your RV being out of commission for days or weeks. 

Having a good water sensor set up won’t guarantee you never have issues with water leaks, but it is a valuable tool for reducing the chance of allowing water damage to build up in your RV undetected.

Electric, Water, and Sewer Accessories

Lastly, let’s finish with a few must-have accessories related to your electric (power), water, and sewer systems: 

7. Portable generator and solar panels

You may already have a generator, inverter, or both within your RV. However, it’s a good idea to consider purchasing a smaller portable generator as well as solar panels.

These will give you a more portable source of power and make you less reliant on your primary power source, with the ability to supplement your power needs with solar.

8. Water filter

It might sound simple enough, but many new RVers set out without thinking about the importance of water cleanliness. 

However, as you travel you’ll be getting your water from various sources, sometimes from local markets but other times from local wells in campgrounds.

To maintain water quality and overall health and safety, it’s best to invest in some kind of water filter, even if you just start off with something simple. 

One popular option among RVers is the Camco TastePURE RV water filter:

9. Holding tank treatment

If you’re new to RVing, holding tank (or sewer) treatment is vital for making sure your sewer lines remain clear and functional, not only minimizing build up but any potential smell. 

The go-to for many RVers is Happy Campers holding tank treatment, a powder that’s easy to use and odor-free. 

You’ll generally want to use holding tank treatment every time after dumping your black tank for maximum effectiveness. 

If a period of time has passed between then and your first sewer use (between seasons, for example), make sure to drop in another treatment before using your toilet again.

Start Your Travels Off Right

Whether it’s your first adventure or your fifth, there are always new and interesting accessories you can pick up that will make your travels easier.

We hope this list provided either a template for those new to RV travel to get you started off right or that you found something new and useful to you if you’re a seasoned traveler.
