In the process of researching ALK's GPS Copilot Laptop Software to add height restrictions to my trip planning, I was able to download the Copilot Laptop 10 Users Manual, which states:
<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">In the United States only, RV routing completely avoids highways that have bridge heights under 12'6" or 13' (whichever you select). It DOES NOT factor bridge heights into consideration on smaller, local roads.
We've been RVing for 20 years and never had an issue with Interstate/Freeway overpasses. Our major concern is with unfamiliar Secondary and "local roads" where it is difficult or impossible to turn around when towing. Our other issue is that we need at least 13'3" of clearance, which forces us from the RV version to the more expensive Truck version.
If you are an experienced GPS Copilot Software user, would you please relate your experiences and opinion with the height restriction of this software and the version you're using?
