Roadtrippers.com

I've been working on a 1-year, 50+ stop trip (essentially a stop per week). For planning purposes, I actually like the trip planner provided by rvparky.com. The biggest downside is that it isn't mobile-friendly. AND- it isn't the guy's primary web site purpose, but it's a great little tool for trip planning.

I found roadtripper.com to be fancy, but klunky to use.
