Welcome to Pennsylvania. Potholes are a way of live.
I don't know if they have been repaired on I-84.
One option is to take I-78 east just past Allentown, PA then 33 north to Stroudsburg, PA. At Stroudsburg pick up US 209 to Matamoras.
From Stroudsburg to Matamoras it's two lane. I have not beet there for a few years but, it was good road. We took our 37' Southwind on that route with no problems.
When you travel in Pennsylvania, assume there will be road work on any route you take. You are usually not disapointed. :E
