A week ago while driving in Cleveland, TN, I came upon a low clearance
that was
not clearly marked and could've taken my camper roof off.
I since purchased the system from
http://www.lowclearances.com and
installed it
to my Garmin 1450LMT.
On my initial "test" run, it detected a 7' 10" in the Chattanooga, TN
area that
I was aware of and is not listed in my trucker's atlas.
I am a retired trucker and trained to be alert for low clearances. I
now
regularly tow a 5th wheel camper that is 13' 3" and would not want to
be
without this great tool.
Thanks for making this great product available!
