I want to do it in four days so I only have to spend three nights in motels. I'm cheap. I figure it will take 15 tanks of gas (400 km/tank), so roughly $650...cheaper than shipping the car and more fun.

interstates do not have tolls. The only time you'll find a toll is if there was some recent project that needs to be payed for (rare), or sometimes when an interstate goes right through the middle of a city, its easier to take an alternate (toll) route to avoid traffic. But generally speaking, no tolls.
