I have had pretty good success with the Rand McNally RV GPS sold by Camping World. I have had bad experiences With Garmin Automotive GPS in car travel, so I am reluctant to trust their products.
The biggest problem with the Rand McNally products is the they age out and stop being reliable after 5-6 years of use. I replaced my first one when that happened. I have had the Rand McNally warn me about high centers, low overhead clearances, road weight limits and other large vehicle issues. I have never driven my RVs in the North Eastern US, so I can't say that the parkway issue would be avoided. These units are based on the Rand McNally Truckers GPS and programmed using their Truckers Guide, so they should.
