1. Go to Lowes and purchase a 10ft and 6 ft section of corner cut laminate counters for a very reasonable price.
2. Remove the headrest from the front seat and fold the seat all the way back.
3. Fold the back seat all the way forward over top of the front seat.
4. Slide in the big counter.
5. Scramble around looking for sweatshirts or towels to cover the big counter so it doesn't get scratched and slide the little counter on top.
6. Tie up the tailgate.
7. Bring the counters home!
I love my prius!
