Considering that he is going to have less autonomy and less flexibility and be working longer hours... 3,000 more a year is fair enough. But he may not get that right away... and he may get more. He may try to ask for 5, and get only 2... just depends on what he is giving up and what he is going to get in return, and if that is worth it too him.
Your worth to the company is how much profit you generate for them, and you have to prove that.
A time limit on re-evaluation is good to agree on upfront, as well as expectations on when and how much the increases will be.
But that can back fire as well if the store does not generate enough profit.
What the boss pulls down a year means nothing. It is not the staff's money that is at risk, or there investment. What WILL matter is how much profit the manager generates at HIS store.
If he doesn't like taking risks then a move could be bad.... store could fail... he could be out of a job, or stuck in one that expects more and does not compensate accordingly.

As well it is good to inquire about bonuses... what is expected to get them and what the range is.
