Low Clearance Alert System for GPS
Low Clearance Alert System for installation on GPS. http://www.lowclearances.com/index.html I don't have experience with this system, but sounds like an alternative to spending $400+ for a new GPS ...

All that system does is use the highway departments info on overpasses etc. as a poi. You can get that info for free in RandMcNally truck maps.
I'm here to tell you that none of the marked bridges are correct. I lived in Chicago and every single truck/RV that sheared off the top of the vehicle on an overpass was 'well within' the clearance marked on the bridge and the warning sign on the road. The road was higher.
Streets are paved and repaved, and repaved which makes them higher which duh makes the clearance marked incorrect. AND many of those bridges, overpasses on many interstates are 'hundreds of years old'!!!
And they don't change the clearance painted on the bridge they just keep painting over it with fresh paint, and the highway department keeps repaving over and over again.....and your GPS just takes that hundred year old clearance dot number and tells you it's ok. :B
IMHO, JMHO, JMHO RV'ers are getting all wrapped up in electronics telling them clearances and blindly going into them if they are within inches of the RV clearance because an 'electronic' device said it was ok. :(
I don't do any overpass that is less than 2 feet of what my RV height is.
