I'm looking at a map and it looks like a direct route from New Haven, Connecticut, to Liberty Harbor RV Park in Jersey City is on I-95 across the George Washington Bridge, and then going south on US 1. It also has the advantage of avoiding tolls.
Is there a reason not to take US 1 south from Fort Lee to Jersey City in a 40-foot motorhome with toad, during non-rush hours? I'm comfortable driving city streets in general. Here's the view from the windshield of my 40-foot motorhome, this time towing a U-Haul trailer through the French Quarter:
And I've driven to Liberty Harbor from the south and didn't have any problem with the city streets on that route. But I don't know if there are other issues, like low bridges or something, on that stretch of US 1 up to Fort Lee.
I assume it will be slow, which is fine with me, but don't want to attempt something that literally can't be done.
