As for the east coast area, around NY/NJ/CT, they have roads marked as parkways (pkwys). Stay off of these. They are marked as passenger cars only and clearances are very often low. If you use a gps system, set it on truck vs car when in this area to avoid parkways. You'd be surprised how many truckers make the wrong choice to enter these.
Just to add to the confusion, there are some parkways that are perfectly suitable for RVs (and trucks) and legal to drive on. Many, probably the majority, are indeed restricted to autos only with good reason, but there are some exceptions to this general policy.
I think all the CT parkways are auto only. The vast majority of NY ones are as well, especially the ones downstate in and around New York City. There are a couple of roads called parkways upstate that are legal for RVs, at least in portions, such as the Robert Moses parkway near Niagara Falls and the Lake Ontario Parkway near Rochester. (The latter you do probably want to avoid as it is in very poor shape, but that's a different issue.) In New Jersey, the Garden State Parkway is a major route and is entirely suitable for RVs.
As a general rule, most numbered state highways are also OK for RVs and trucks, although occasionally there are low clearances. A few are definitely not suitable. Vermont route 108 through Smuggler's Notch is a great example of the latter; every year, despite prohibitions and very clear signs, a few misguided trucks get wedged in between the rocks and block the pass until they can be extricated (at no small expense).
