Thanks for that tip; I did see that that for just the van/car rig would be ~$22-23, so I'll definitely check out how 206 looks.
While I definitely see the usefulness of US-206, as described by glc above, it is completely because it is toll-free. My husband detested that highway in that area, because it was like driving on street surfaces (including stop signs and traffic lights) for lots of miles. Perhaps we would have found it better if we were avoiding huge tolls. We just used it because it went where we needed to go (Princeton to Stanhope).
