I use a Garmin RV 660LMT and found it to be a good guide. You enter the dimensions of your rig, including height, and it plans your routes accordingly.

I ignored it and, sure enough, the clearance sign said 14' 2" as I approached. I could not stop at that time and proceeded under it without incident. It is possible that I overestimated my height and the highway department underestimated it, both parties being conservative.
FWIW, the RV GPS units only have a d.b. that contains about 1500 data points with low clearance. Adding the Route-1 d.b. gives you over 7,000...
