Honestly, I almost threw a perfectly good drill across my driveway the first time I tried to figure out how to install side cameras on RVs. Wasted three hours, swore off DIY forever. Then I remembered my uncle’s old camper, the one with the fishtail antennas and the questionable upholstery.
That little beast had more personality than most modern rigs, and so did the mess of wires he had running to his backup camera setup. He always said, ‘If it ain’t broke, don’t fix it,’ but then he’d spend a weekend trying to ‘fix’ it anyway. Sound familiar?
You’re probably here because you’ve seen those blind spots on your RV, especially when changing lanes or parking. Those aren’t just minor annoyances; they’re hazards. Getting this done right matters, and frankly, some of the advice out there is just… baffling.
Why You’re Actually Doing This (beyond Just ‘seeing Better’)
Look, nobody wakes up wanting to spend a Saturday wrestling with wires and drilling holes in their RV. You’re doing this because the sheer terror of clipping something — or someone — when you’re maneuvering this land yacht is starting to outweigh the annoyance of a DIY project. It’s about peace of mind, plain and simple. That feeling when you *know* what’s on either side of your rig? Priceless. My first RV was a beast, and I swear I could barely see the nose of it, let alone what was happening twenty feet back or to the sides.
Think of your RV like a really, really big, expensive, mobile apartment. You wouldn’t drive a house blindfolded, right? Side cameras are the eyes on the outside of that house. They’re not just for parking; they’re for those awkward merges on the interstate where you’re trying to judge if that semi is actually in your lane, or when you’re navigating a tight campsite with trees that look like they’re actively trying to scratch your paint job.

The Gear You Actually Need (and What to Avoid)
There’s a glut of camera kits out there, and I can tell you from bitter experience, most of them are junk. I once spent around $350 testing four different kits before I found one that didn’t flicker like a bad horror movie scene or die after a month in the rain. The marketing hype is thick enough to cut with a knife, promising crystal-clear images that look more like a blurry potato cam in real-world conditions.
Forget those kits that claim ‘universal fit’ unless they actually provide a decent range of mounting brackets. The curve of an RV wall isn’t the same as a car door. You want cameras with good night vision – that means IR LEDs, not just relying on ambient light. And for wiring? Look for marine-grade connectors if you can, or at least something that feels substantial, not like a Christmas ornament wire. Waterproofing is non-negotiable. You’re essentially mounting electronics on the outside of a vehicle that experiences every kind of weather known to man.
The monitor is another story. Some are tiny, like a postage stamp, others are giant iPad-sized things that block your view. I prefer something around 5-7 inches, mounted where it doesn’t demand your attention but is easily visible at a glance. The touch screen on one system I tested was so unresponsive, it felt like trying to operate a smartphone with oven mitts on.
Wiring Wisdom: Don’t Make My Mistakes
This is where most people get tripped up. You can’t just jam wires through random holes. You need to find existing grommets or drill new holes strategically, sealing them up tight afterward. Silicone sealant is your best friend here. I learned this the hard way when my first attempt resulted in a minor leak after a heavy rainstorm, and I had to pull everything out again.
Consider the power source. Some cameras draw directly from your running lights or ignition. Others have separate power wires. You’ll want to tap into a constant 12V source that’s fused, ideally one that’s switched with your ignition so the cameras don’t drain your batteries when parked. The wiring diagram that came with my first kit was hand-drawn by someone with the artistic talent of a toddler. Useless. Consulting an RV repair manual or even a forum dedicated to your specific RV model can save you hours of head-scratching.

Mounting the Cameras: Location, Location, Location
Everyone says ‘mount them under your mirrors.’ Sure, that’s common, but is it optimal? Not always. Think about the viewing angle you *actually* need. Do you want to see the lane next to you, or do you want to see the entire side of your RV and the immediate vicinity? For lane changes, placing them slightly forward of the mirror and angled to capture traffic in your blind spot is key. For general side-viewing, lower and further back might be better.
Drilling is scary, I get it. But if you don’t drill, you’ll likely end up with tape failing or brackets that don’t sit flush. My advice? Measure twice, drill once. Use a small pilot hole first to confirm your location and depth. Then, use a step bit or a hole saw appropriate for the wire gauge. Always have a helper inside the RV to guide the wires and to confirm you aren’t drilling into anything vital.
Consider the aesthetic too. You don’t want these giant black boxes sticking out like a sore thumb. Many kits come with small, unobtrusive cameras that blend in reasonably well with the RV’s siding. The tactile feedback of the drill bit biting into the fiberglass is a sound you’ll get used to, but it’s always a little nerve-wracking.
The ‘no Drill’ Myth
Some people swear by heavy-duty VHB tape. And for a lightweight camera on a perfectly flat surface? Maybe. But on an RV, with its curves, vibrations, and exposure to sun and rain? It’s a gamble. I watched a friend’s backup camera, which was ‘securely’ taped, fly off on the highway last summer. Thankfully, it didn’t cause an accident, but it was a $150 piece of plastic littering the interstate.
Stick with mechanical fasteners. It’s the only way to be sure. Think of it like building a fence; you wouldn’t just rely on duct tape to hold the posts, would you? The structural integrity of your RV is paramount, and while you’re adding new holes, doing it right with proper sealing prevents bigger, more expensive problems down the road.

Connecting the Dots: Power and Display
This is where the system comes to life. You’ll typically run the camera wires to the front of your RV, where they’ll connect to a distribution box or directly to your monitor. Choosing where to mount the monitor is a personal preference, but I like mine on the dash, slightly to the right of the steering wheel, angled so I can see it without taking my eyes off the road for too long. The glare on some screens can be brutal in direct sunlight; look for anti-glare coatings if you can.
Powering the system is another point of confusion. Some RVs have readily accessible 12V fused accessory circuits. Others are a bit more cryptic. When in doubt, find an RV electrician or consult a reputable RV repair manual. Incorrect wiring can fry your new cameras, your monitor, or worse, cause a short that damages your RV’s electrical system. The humming of the RV’s engine and the occasional creak of the chassis are the ambient sounds you’ll hear while doing this part.
A common mistake is tapping into a circuit that only has power when the engine is running. This is fine for some cameras, but if you want to use them for general observation while parked, you’ll need a constant 12V source. I spent an entire afternoon tracing wires with a multimeter because I initially plugged into the wrong accessory port, only to find my cameras went dead every time I turned off the ignition.
| Component | My Verdict | Notes |
|---|---|---|
| Cameras (Side View) | Good Quality, Weatherproof | Look for wide-angle lenses (120-150 degrees). Avoid generic brands that lack specific RV-oriented designs. |
| Monitor | 5-7 Inch Touchscreen | Anti-glare is a must. Ensure good brightness for daytime use. Some integrated mirror monitors are neat but can be pricier. |
| Wiring Harness | Heavy Gauge, Waterproof Connectors | Don’t skimp here. Cheap wire leads to signal loss and failure. Marine-grade is ideal. |
| Mounting Hardware | Secure, Non-Corrosive | Stainless steel screws are best. Consider angled mounts if your RV has curved surfaces. |
| Sealant | High-Quality Silicone | Essential for preventing leaks after drilling. Don’t use cheap caulk. |
Testing and Troubleshooting: The Final Frontier
Once everything is connected, it’s time to test. Turn on your RV’s ignition. You should see your monitor power up and display images from your side cameras. Check each camera individually. Does the image look clear? Is it the correct angle? Are there any flickering issues?
If a camera isn’t working, retrace your steps. Check all connections. Is the power wire secure? Is the video cable plugged in all the way? Sometimes, a loose connection is all it takes. I once had one camera out because the connector was just slightly loose at the distribution box. Took me an hour to find it because I was convinced I’d wired something wrong internally.
Also, test the cameras in different lighting conditions – daytime, dusk, and at night. The IR LEDs should activate automatically in low light. If you’re experiencing interference, it could be from other electronic devices, although this is less common with well-shielded cables. According to the National Highway Traffic Safety Administration (NHTSA), rearview and side-view cameras are a proven safety feature that can reduce accidents.

People Also Ask (paa) — My Two Cents
Can I use my phone as an RV side camera?
Technically, yes, with some Wi-Fi camera systems designed for this. But honestly? It’s often a clunky experience. You’ll have lag, potential connection dropouts, and a small screen that distracts from driving. I tried a Wi-Fi setup once, and the latency was so bad I almost backed into a shopping cart because the image on my phone was a good two seconds behind reality. Not worth the frustration for something so critical to safety.
How many side cameras do I need on an RV?
Most people opt for two – one on each side. This covers your primary blind spots for lane changes and general awareness. Some larger RVs or fifth wheels might benefit from a third camera further back on the side for a wider field of view, but for the typical Class A or C, two is usually sufficient and manageable for wiring.
Do RV side cameras work in the dark?
Yes, good ones do. They typically have infrared (IR) LEDs that illuminate the area around the camera. The image will appear black and white, but it should be clear enough to see obstacles, vehicles, and other hazards. The range and clarity will vary by camera quality, but most modern units are quite capable.
Conclusion
So, there you have it. Installing side cameras on RVs isn’t rocket science, but it’s definitely not a ‘plug and play’ operation either. It requires patience, a willingness to get your hands dirty, and the understanding that cutting corners here will only lead to more headaches and potential damage down the line.
Remember my initial drill-throwing incident? It was a humbling reminder that even experienced people make mistakes. The key to how to install side cameras on RVs successfully is preparation, using the right tools, and not being afraid to seek advice when you’re stuck. You’ve got this.
Before you even pick up the drill, map out your wiring run, double-check your power source, and gather all your sealant and fasteners. A little extra planning upfront saves a lot of ‘why is this leaking?’ later.
