Our Verdict

The Garmin dezl OTR1010 wins on screen size, traffic quality, and ease of map updates. The 10-inch screen is a genuine comfort improvement for all-day navigation, and Garmin's traffic algorithms consistently find better routes in real-time.

The Rand McNally TND 750 fights back with marginally better truck routing data, reflecting their deep trucking heritage. Drivers who prioritize routing accuracy over screen size may still prefer Rand McNally.

Both are excellent truck GPS units. The decision often comes down to screen size preference and brand loyalty. If you have used Rand McNally's pocket-sized trucking atlas, their GPS will feel familiar.

Frequently Asked Questions

Most truck dashes have plenty of space for a 10-inch unit. The larger screen reduces eye strain during long driving days and makes navigation easier in complex interchanges. Few drivers who upgrade to a 10-inch screen want to go back to 7 inches.
Yes, both allow custom vehicle profiles including height, weight, length, and width for routing around restrictions. They work well for RVs, box trucks, and combinations when programmed with correct dimensions.
Dedicated truck GPS units provide truck-specific routing that smartphone apps (even Trucker Path and CoPilot) cannot fully match. For consistent low-bridge avoidance and weight restriction compliance, a dedicated unit is worth the investment.
