A dash cam for a motorhome is typically installed on the front windshield near the rearview mirror, with a wired rear camera recommended for large vehicles, providing crucial coverage for towing, lane changes, and parking.
Installing a dash cam in a motorhome isn’t just about recording the road ahead. Your rig is longer, taller, and likely towing something, which means blind spots and parking challenges multiply. A properly installed camera system—front and rear—gives you real accident evidence and makes maneuvers safer. Here is exactly where to place everything, how to route the cables, and what to avoid.
Best Dash Cam Placement for Your Motorhome
The best spot for your front dash cam is directly behind the rearview mirror or slightly to the passenger side. For motorhomes, the same windshield rule applies, but the top of the windscreen is usually ideal because it offers a clear, unobstructed view. The Practical Motorhome guide stresses that the camera must not block the driver’s field of vision, so mounting it high and out of the immediate line of sight is the correct approach.
For rear cameras, you have three main approaches. A wired rear camera offers the best video quality and reliability, but the cable run can be 30–50 feet for a full-size Class A motorhome. Wireless rear cameras are simpler to install but can suffer from reduced quality and signal drops due to the long metal body of the vehicle. Many factory backup camera systems are not recorded and are unsuitable for incident documentation, so they don’t replace a dedicated dash cam.
Step-by-Step Installation Guide
The installation process is straightforward if you follow the correct order. First, clean the windshield or mounting surface with a glass cleaner or alcohol wipe, then let it dry completely. Before removing the adhesive backing, do a test fit to check the camera angle on the screen or app. Once the position is confirmed, attach the mount firmly.
Route the power cable along the headliner, down the A-pillar, and to the fuse box. This standard method keeps the cable completely hidden and avoids interference with airbags. Use a hardwire kit to connect to the fuse box. After powering up, be sure to set the date and time, insert a microSD card, and format it before driving. For a rear camera on a long motorhome, the wired installation is more complex because the cable must run the full length of the vehicle, typically through ceiling panels and weather stripping.
Dash Cam vs. Rear Camera Options: What Works for Your RV
Choosing the right configuration depends on your motorhome’s size and needs. The table below summarizes the best approach for common RV types.
| Motorhome Type | Recommended Camera Setup | Key Considerations |
|---|---|---|
| Class A (35+ ft) | Front wide-angle + wired rear camera | The wired rear camera is essential for reliable coverage at this length. |
| Class C (with cab) | Front wide-angle + wired rear camera | If you tow a toad (a small car), add a wireless camera on the toad’s rear for extended coverage. The wired rear unit handles the primary rear view. |
| Any motorhome | Front camera only | A bare-bones option that covers forward incidents but leaves massive blind spots. Not recommended for safe lane changes or backing up. |

Common Mistakes to Avoid
Several installation errors can ruin an otherwise good setup. Mounting the camera too low on the windshield is the most frequent problem—it blocks your view and misses the optimal angle. Leaving the power cable dangling across the dash looks sloppy and can interfere with driving. Skipping the test fit before sticking the mount means you might end up with a crooked or poorly aimed camera.
Other critical misses include forgetting to install or format the microSD card before your first trip, and assuming the motorhome’s factory backup camera will record usable evidence for an accident. For long vehicles, using a wireless rear camera often leads to reliability issues due to the metal body blocking the signal.
Finally, ensure your camera is positioned so it does not block the driver’s view—the top of the windshield is the safe zone. When routing cables, especially near the A-pillar, keep them clear of airbag deployment zones to avoid any safety hazards.
FAQs
Can I install a dash cam in a motorhome with an airbag?
Yes, provided you route the cable along the headliner and down the A-pillar, not directly over the airbag area. This is the standard safe method that keeps the cable hidden and avoids interfering with airbag deployment.
What’s the best rear camera setup for a Class A motorhome?
Do I need a separate microSD card for the camera?
Yes, your dash cam will require a high-endurance microSD card (usually 64GB or 128GB). It must be inserted and formatted inside the camera before first use, as formatting ensures the camera can properly write and overwrite files.
