Its not unusual for hypermilers to get better city mileage than highway mileage. The wind resistance plus rolling resistance on the highway ends up keeping it lower. In the city, you really only deal with rolling resistance so there is a lot more area for gains.

Pulse and glide is the ultimate highway technique if you can pull it off, but its a lot of work in an automatic. Using driving with load if you can't pulse and glide is really your only alternative. Other than that, slowing down as much as possible to eliminate that wind resistance is going to net you good gains. If its not too windy out you can try to find a semi and stay 3 or so seconds behind it. This is good for a small gain and is still a safe distance behind the truck.
