RV GPS
I have a GO-720 Tom Tom GPS and want to upgrade to TomTom 1605M RV GPS. Can someone share his experience with 1605M . Thanks

Whenever you get a new GPS, I strongly recommend picking a route of 30-40 miles that you know well.
Drive the route with the GPS set for various options. LEARN what it will and will not do, how the various options/ settings work and how they impact the routing.
Low clearance avoidance only works if the highway department data is current and correct. The GPS companies do not compile their own data, they work from data made publicly available by the various state highway departments.
One fault I've found with all brands of GPS about low clearance is there is no consideration of the approach road.
i.e. I know of some low railroad underpass which are marked at 12'6" in my area. However because the height is marked as the height at center of the underpass, and the road dips to get that clearance, a trailer 11'7" tall with TV rear axles and trailer axles 22' apart will hit the bottom of the underpass.
The I-5 bridge in Washington which was knocked down a couple years ago was because the load had clearance until the TV went off the bridge and the road dropped a couple feet. That raised the rear of the load almost 18 inches higher, taking out several bridge supports.
Always remember a GPS is advisory, not ever to be taken as totally accurate. (And I have my rig specs in my RV GPS set to 14" taller than my TT really is.)
