Quick verdict
The Garmin dēzl OTR720 is our recommended choice for drivers who want verified tools for truck navigation and arrival planning. The Rand McNally RANDTAB7 is better for drivers who want longer battery life, a higher screen resolution, and an Android-based navigation tablet.
Both devices have approximately 7-inch screens and support truck-specific routing. They also provide hazmat support, bridge height warnings, steep grade warnings, and weigh station alerts. Both include map updates and live traffic, weather, and fuel prices.
The main differences are screen resolution, weight, battery life, device type, and live service connections.
The Garmin weighs 8.5 oz and has a stated battery life of 1.5 hours. The Rand McNally weighs 16 oz and has a stated battery life of 5 hours.
For most drivers, the choice depends on verified truck-specific features, battery life, and how they want to connect to live services.
Why choose Garmin dēzl OTR720?
Choose the Garmin dēzl OTR720 if you want a lightweight truck GPS with verified tools for arrival planning.
The OTR720 includes satellite arrival imagery. This feature gives you an overhead view of your destination before you arrive. It can help you identify truck entrances, access roads, and loading areas.
The Garmin also provides community loading dock information. This can help you find loading areas at delivery locations that you do not know.
Other verified features include a CAT Scale locator, PrePass support, truck parking information, and weight limit warnings.
These features are not verified for the RANDTAB7. This does not mean that the Rand McNally device does not have them.
The OTR720 has a 6.95-inch screen with a resolution of 1024 × 600 pixels. It measures 6.97 × 4.17 × 0.75 inches and weighs 8.5 oz.
The Garmin is slightly smaller and 7.5 oz lighter than the RANDTAB7. Its lower weight can make it easier to move between trucks.
The OTR720 uses a compatible smartphone and the Garmin dēzl app for live traffic, weather, and fuel prices.
Its stated battery life is 1.5 hours, which is shorter than the RANDTAB7’s 5 hours.
Choose the OTR720 if verified arrival planning tools, truck-specific information, and lower device weight are your priorities.
Why choose Rand McNally RANDTAB7?
Choose the Rand McNally RANDTAB7 if you want an Android-based truck navigation tablet with longer battery life.
The RANDTAB7 has a 7-inch screen with a resolution of 1280 × 800 pixels. This is higher than the Garmin’s 1024 × 600 resolution. The additional pixels can help display small text and map details more clearly.
The RANDTAB7 has a stated battery life of 5 hours, compared with 1.5 hours for the Garmin. This gives you more time to use the device without vehicle power. It can be useful when you plan routes or check information away from your truck.
Another advantage is how the RANDTAB7 connects to live services. It uses Wi-Fi or an internet connection for live traffic, weather, and fuel prices. You do not need a dedicated smartphone companion app. However, an internet connection is still necessary for these services.
The RANDTAB7 measures 7.25 × 4.5 × 0.75 inches and weighs 16 oz. It is larger and heavier than the Garmin, so check the available mounting space before you buy.
Like the Garmin, it supports truck-specific routing, hazmat support, bridge height warnings, steep grade warnings, and weigh station alerts.
Some additional features, such as PrePass, CAT Scale locations, truck parking information, satellite arrival imagery, and community loading docks, are not verified for the RANDTAB7. This does not confirm that these functions are absent.
Choose the RANDTAB7 if longer battery life, higher screen resolution, and live services without a dedicated smartphone app are more important to you.

Final recommendation
We recommend the Garmin dēzl OTR720 for drivers who frequently travel to unfamiliar delivery locations. Its verified satellite arrival imagery, community loading dock information, CAT Scale locator, and truck parking information provide useful tools for daily truck operations. Its smaller size and lower weight are also advantages.
Choose the Rand McNally RANDTAB7 if you need longer battery life or prefer an Android-based navigation tablet. It provides a higher screen resolution and a stated battery life of 5 hours. It also connects to live services through Wi-Fi or an internet connection without a dedicated smartphone app.
Both devices support the same verified core truck routing functions, except that weight limit warnings are not verified for the RANDTAB7. This does not mean that the RANDTAB7 lacks this feature.
Neither model has a verified advantage in routing accuracy.
Compare current prices, available mounting space, and your connection requirements before you buy.
Both GPS units can calculate routes based on truck dimensions and restrictions. However, map information can be incomplete or out of date. Always follow road signs and check bridge clearances, weight limits, and local restrictions.
