Why choose Rand McNally RANDTAB8?
Choose the Rand McNally RANDTAB8 if you want a larger display for truck navigation.

Final recommendation
We recommend the Rand McNally RANDTAB6 for drivers who want a compact truck GPS. It is smaller, lighter, and provides the same verified truck navigation and connected features as the RANDTAB8.
Choose the RANDTAB8 if a larger screen and rear camera are more important than compact size and low weight. Its 8-inch screen gives you more space to view maps and route information. Its Android tablet design and rear camera can also be useful if you want these functions in the same device.
Neither model has a verified advantage in truck-specific routing, battery life, or live services. Satellite arrival imagery and community loading dock information are not verified for either model. This does not mean these features are absent.
Compare the current prices and check the available mounting space before you make a decision.
Both devices can calculate routes based on truck dimensions and restrictions. However, GPS information can be incomplete or out of date. Always follow road signs and check bridge clearances, weight limits, and local restrictions.
