White class 8 pulling a DRV 5th close to clear lake CA

You can definitely go a long way on a fill up. I recently drove out to Oklahoma and back (to pick up my new DRV). I filled up once on the way out and once on the way back. Its nice to stop when you want rather than when you have to. Its also nice to have the capacity to go until fuel prices are more reasonable rather than get stuck with whatever is available when you need it.
