If it runs and drives and stops, and has had no major problems in the past year or so driving locally then drive it to Maine.

I had driven my 52 1 ton around town and never out of the county for a few years before I took a trip around the country in it, 8,000 miles with only a broken fan and a bad generator bearing.
You really don't know till you try do you?
If it works around town chances are it will be fine on a trip.
