1. Garmin RV 890: Best Overall

Garmin RV 890

🛒  Check Price on Amazon →

The Garmin RV 890 tops our list for its dedicated RV routing. We researched owner feedback and spec sheets and found that its custom routing based on vehicle dimensions significantly reduces the risk of low bridges or narrow roads. The 8-inch display is bright and responsive, making it easy to see at a glance. Voice control works well for hands-free operation, a key safety feature.

However, the mount is not as versatile as some competitors; it relies on a suction cup that may not stick to textured dashboards. Some owners reported occasional slow route recalculations in dense urban areas. This GPS is ideal for RVers who want a dedicated navigator, but truckers may prefer a unit with more robust mounting options.

  • Large 8-inch screen with high resolution and automatic dimming
  • Custom routing based on RV height, weight, length, and propane restrictions
  • Built-in Wi-Fi for map updates and live traffic without a computer

Pros: Excellent routing for large vehicles; Intuitive interface with voice commands
Cons: Magnetic mount not included for all surfaces

2. Garmin dezl 770 LMT-S: Best for Trucks

The Garmin dezl 770 LMT-S is a strong choice for commercial truck drivers. In our evaluation, its truck routing accurately avoided low bridges and weight-restricted roads based on user reports. The 7-inch display is clear and readable even in direct sunlight. Lifetime map updates and traffic are included, which adds long-term value.

On the downside, the processor can feel slow when entering addresses or recalculating routes. The optional dash cam is a nice idea but adds cost and complexity. This unit is best for truckers who want a reliable, no-frills navigator, but RV owners with larger vehicles might prefer the RV 890’s larger screen.

  • Truck-specific routing with height, weight, and hazmat restrictions
  • Includes lifetime maps and traffic via subscription
  • Optional dash cam add-on for recording (sold separately)

Pros: Reliable truck routing with up-to-date points of interest; Easy to read in sunlight
Cons: Interface can be sluggish at times; Dash cam not included

3. Rand McNally TND 750: Best for Custom Routes

Rand McNally TND 750

🛒  Check Price on Amazon →

The Rand McNally TND 750 stands out for its advanced route planning. We compared its features with others and found that the ability to add multiple waypoints and avoid specific road types is excellent for RVers who want scenic routes. The pinch-to-zoom and gesture controls make the interface feel modern. Wi-Fi connectivity simplifies updates.

However, some owners report software freezes that require a restart. The mount, while adjustable, can wobble on bumpy roads. This GPS is ideal for those who love planning detailed trips, but it may not be for drivers who want a simple, set-it-and-forget-it device.

  • Advanced route customization with multiple waypoints and road preferences
  • Built-in Wi-Fi for map updates and traffic
  • Pinch-to-zoom and gesture controls for easier interaction

Pros: Highly customizable routes; Good for multi-stop trips
Cons: Occasional software glitches; Mount can be wobbly on rough roads

4. TomTom Trucker 600: Best Value

The TomTom Trucker 600 offers solid truck navigation at a reasonable price point. Based on owner feedback, its routing is accurate and the vehicle profile settings work well. The large buttons are useful for drivers wearing gloves. Lifetime maps add ongoing value without extra cost.

The 6-inch screen is smaller than most rivals, which can be a drawback for older eyes or when split-view is needed. Lack of voice control means more manual interaction. This is a good budget option for truckers who prioritize function over screen size, but RVers may want a larger display.

  • Truck routing with vehicle profile for height, weight, and load
  • Lifetime world maps and traffic alerts
  • Simple interface with large buttons for gloved hands

Pros: Affordable for the features; Reliable routing for truckers
Cons: Smaller screen than competitors; No voice control

5. Garmin RV 785: Premium Pick

🛒  Check Price on Amazon →

The Garmin RV 785 is a premium option for RVers who want a dedicated navigator with extensive points of interest. Our research shows its RV park directory is comprehensive and regularly updated. The voice control is responsive and reduces distraction. The display is bright and easy to read.

The main drawback is the cost, and map updates require a subscription after the first year. Some owners find the interface overwhelming with too many options. This is best for RVers who want the best possible experience and are willing to pay for it, but budget-conscious buyers may look elsewhere.

  • Preloaded directory of RV parks and services
  • Voice-activated navigation and hands-free calling
  • Bright display with automatic dimming and glare reduction

Pros: Excellent RV database; Smooth voice control performance
Cons: Higher price point; Maps require subscription after first year

6. Rand McNally OverDryve 7: Best with Dash Cam

Rand McNally OverDryve 7

🛒  Check Price on Amazon →

The Rand McNally OverDryve 7 combines navigation with a built-in dash cam, a unique feature. In our evaluation, the safety alerts for collision and lane departure are helpful. The 7-inch display is decent, and voice control works reasonably well.

However, the dash cam video quality is not as sharp as dedicated units, and the battery lasts only about 30 minutes when not plugged in. Some users report the interface can lag. This unit is best for those who want a single device for navigation and recording, but serious dash cam users should consider separate units.

  • Built-in dash cam with forward collision and lane departure warnings
  • Voice control and hands-free calling
  • Wi-Fi for map updates and traffic

Pros: All-in-one navigation and dash cam; Safety alerts are useful
Cons: Dash cam video quality is average; Battery life is short when unplugged

7. Garmin DriveSmart 65: Best for Cars & Small RVs

Garmin DriveSmart 65

🛒  Check Price on Amazon →

The Garmin DriveSmart 65 is a solid car navigator with a large screen. We found its driver alerts and points of interest useful for general travel. Voice control works well, and the display is bright.

However, it lacks truck or RV-specific routing, meaning it may direct you onto roads unsuitable for large vehicles. The mount is not as sturdy for heavy vibrations. This GPS is best for smaller RVs or passenger vehicles, but owners of large RVs or trucks should choose a dedicated model.

  • Driver alerts for sharp curves, speed changes, and red light cameras
  • Voice-activated navigation and hands-free calling
  • TripAdvisor and Foursquare points of interest

Pros: Large screen for the price; Good driver alerts
Cons: Not optimized for large RVs or trucks; No custom vehicle profile

Frequently Asked Questions

What features should I look for in a GPS for RVs and trucks?

Look for custom routing based on vehicle height, weight, length, and hazardous materials. A large, bright display, voice control, and lifetime map updates are also important. Safety features like lane departure warnings can be beneficial.

Can I use a regular car GPS in an RV or truck?

We do not recommend it. Regular car GPS units may route you onto roads with low bridges or weight restrictions. Dedicated RV and truck GPS units include vehicle profiles to avoid such hazards.

How often should I update the maps on my GPS?

We recommend updating maps at least once a year to ensure accurate routing. Many units offer lifetime map updates, which add value. Outdated maps can lead to incorrect directions.

Do I need a GPS with a dash cam?

It depends on your needs. A combined unit saves space and provides safety alerts, but dedicated dash cams often have better video quality. For most users, a separate dash cam is preferable.

What size screen is best for RV and truck GPS?

We recommend at least a 7-inch screen for easy readability. Larger screens (8 inches) are even better for older eyes or when using split-screen views. Smaller screens can be harder to read while driving.

Our Verdict

After our research and comparison, the Garmin RV 890 is our top pick for most RV and truck owners due to its excellent routing and large display. For a runner-up, the Garmin dezl 770 LMT-S offers reliable truck-specific navigation at a slightly lower price point.
