I think you would make it fine. You have (at least) 2 options to approach the big hills:
1. Max MPG: Leave it in 5th or maybe 4th if necessary, and floor it. You will use a lot of battery assist, and this will help your mileage, but really pound your battery. You can watch your charge meter drop, drop, drop, while your jaw clenches and sweat breaks out on your forehead as you try to will the car up the road, until you have no choice but to downshift.
2. Low stress: Drop it into 3rd (or even 2nd if you're in a big hurry), and scoot up the hill. No, this isn't the best approach for max efficiency, but you will still use 3 or 4 times less gas than your truck.
Since your route is a little extreme, it might be best for you to try your usual drive in an Insight if at all possible.
