You must also be able to climb the hill efficiently, e.g. in top gear. My car suffers more than most on hills because it does so well on flat land due to the small displacement and tall gearing.
Regarding the 500lbs of ballast: that will add to your rolling resistance, and raise the stakes if you have to brake. Hills don't make P&G any more effective, just easier to do.
