RV Trip Routing From CA to FL

Is there not a program that will plot your route and you can tell it how many hours a day or how many miles per day you want to go?
I could swear Ive used a program that did this but I cannot remember which one it is.

I am still using the 2010 version of the "Trailer Life Directory Campground Navigator" which was produced by Undertow. The partnership between Trailer Life and Undertow was dissolved after the 2010 Version of the software. A recent version produced by Undertow is an identical mapping program but without the amount of campground information that was in the 2010 program.

It is unfortunate that Trailer Life did not continue this valuable computer program. It was the best for trip planning at the computer.
