If there is a current one I haven't found it.
We use RV Trip Wizard RVTW for planning, it is excellent, then switch to, DeLorme's Street Atlas on my laptop for actual navigating. It was abandoned in 2016, MS abandoned Streets and Trips in 2012. I have a copy of that too. Street Atlas is OK but slow to adjust to the gps for most of the trip until the last few miles when we often just use Google on my wife's phone. All this is a PITA. RVTW has a phone navigation app, RV LIfe, but I haven't tried it yet.
