I always use the trip from Charleston out west as a gauge. I fill up the tank just outside of Charleston and see how far west I can make it before I have to stop. Mount Vernon, Illinois is the usual stopping point, a little over 6 hours away. I actually haven't noticed a difference with either 1.) the AC on or off and 2.) equipment on the roof, including a large cargo carrier.
If there is any reduction in MPG, it is probably so small that the monetary cost is negligible.
Here are a few of my tactics, some of these have already been mentioned:
1.) Carpool! 2 people cuts your costs in half. Four people reduces them by 75%!
2.) Hotel choice. Be willing to endure some less than 'five-star' hotels. We've also used hotels.com many nights to get decent rates.
3.) Sleep in the car if you're traveling solo. Be wise and careful about where you park so you don't make yourself a target for criminals and/or a subject to be harassed by suspicious police/security guards/property owners.
