RV GPS
Looking for suggestions on a GPS unit similar to a trucker GPS...one that you enter your rig dimensions and you are routed on roads that will accommodate you...particularly around low clearance bridge...

I have the Garmin RV760LMT with up to date maps. All I have to do is turn it on and it will get me lost...... I never trust it any more but use the trucker's atlas and it has never been wrong. The Garmin was wrong many, many times. Can you tell I really don’t trust the Garmin?
I'm still using one of the oldest first large screen talk to speech TomTom's and everything works just fine on it. I don't even update it. It updates itself regarding new roads etc.
From what I read on forums the newer the GPS's got and with requiring updates every other week, the stupider they got.
That said please do not trust ANY GPS regarding bridge height when driving your RV!
In Chicago alone 80% of the bridges are NOT as high as what they are marked for. And that is where GPS's get their info from.
The majority of bridges are old. They were marked with their height when they were built. AND the streets have been resurfaced over and over and over again sometimes adding up to 2 to 4 inches or more of road material which equals far LESS clearance. And no one goes back and remeasures them to enter into the county records.
I think the trucker maps have access to actual heights on bridges but I'm sure not for all of them.
That is why you see so many trucks on the news every week getting stuck under them!
