I live in Syracuse part time. MY preferred route in my MH is 81 south to 380 in Scranton. 80 to 80 east and then for you New Jersey turnpike (toll)to the correct exit.
This route is all controlled access and no tolls till NJT
From Buffalo you could get on 390 south justt before Rochester which will take you to 86/17 east to Binghamton where you can catch 81S to Scranton. Parts of this 86/17 route are not controlled access as yet and go through a town
I am doing this run on Friday from Syracuse only I will be going out to Long Island.
Depending on your speed the places to stay enroute if needed would be the Flying J in Gibson PA. A rest area just after the 380/80 junction about 2 hours 15 minutes from NYC at 55 miles per hour. The outlet mall about 15 miles west of the PA/NJ line. A rest area at Mile marker 7 in New Jersey about 1 hour 20 minutes from NyC
No hazmat concerns either route I have outlined
