New HD install scheduled, should I keep the old dish?

[EmpireState]

I'm upgrading to the vip722 soon and the service rep asked if I wanted to leave the old dish on the roof or have the installer remove it when they install the new dish. The old one is at least 5 years old so I'm wondering why I would want to keep it. Anyone have any ideas?

-thanks

The only real reason to keep the dish is if you anticipate going camping and needing a second dish at that particular site.
