the information.. other than road data...
is only as good as the State or US Government gives the GPS companies...
so weight, height, restrictions. (Propane) will always be hit or miss.. my opinion. just like routes, around or thru cities..
the KEY reason I have/use a GPS.. is for when I am lost... a detour.. or something turns me around...
my very first time I used a GPS .... years ago.. I was going to someone's dinner party.. never been there... the GPS put me in a driveway ... 1/4 mile off... RIGHT Street... wrong block. I learned ...
^^^^Thank You ^^^^^ for the propane warning and tunnels... I have forgotten about that... a big trip in 2 weeks..
