I finally got Trip Planner to work for me. Simple fix, no idea why it works. I just went into the browser settings and allowed popups for the trip planner page. Yes, I know, there are no popups on the Trip Planner. But allowing them fixed all the problems I've had, including not showing a planned route, and not allowing me to add a stop. Nothing else worked, and I tried everything.
Now that I have it working, I have to say it's sort of useful, but it's also sort of lame in other ways. It won't warn you of some well-known RV restrictions, like no RVs of any size on any NY state road called a "parkway" (e.g. the Taconic Parkway), and no non-empty propane tanks of any size on any vehicle in Boston tunnels (even if the tank is turned off--and yes, the Mass. state police have been known to pull RVs over, and it's a huge fine). And Trip Planner doesn't come close to flagging all the low-clearance bridges on non-major roads, though that's a tall order and I don't think it's reasonable to expect it to (but I really wish it did).
And given all the complaints on the Forum about Trip Planner not working, with no helpful response just about ever from Good Sam support, I'd say there's no support or maintenance for Trip Planner, which I'd guess means important new RV/road restrictions probably won't make it into the planner.
But hey, it's free for members, so while it isn't the great perk that it would be if Good Sam put some work into it, it's an OK one that ought to be used with caution.
