Mapquest can plot your trip pretty well and you can make changes to their suggested route.
Also, I have made similar long trips (though not quite as long). My travel tips are:
- Take a cooler and stock with your favorite drinks. You don't have to stop to buy along the way and its a lot cheaper too.
- Bring along snacks like chips, apples, etc.
- Be sure to bring along plenty of tunes, CDs, tapes, whatever.
- Wear comfortable clothing and shoes.
- Stop every three hours or so to take restroom breaks and to stretch.
- Take some simple tools and motor oil, etc.
Good luck and happy motoring!
