Also keep in mind timing. You can't quit your job a month early to "help pack." The benefits are for following your spouse or family to a new location because it was either that or be alone. Got it?
That means in a perfect world, you make your husband do the packing, and you work your job right up until the day you drive the U-Haul to your new location. While in transit you're not able and available unless you leave late on Friday night and arrive at the new location first thing Monday morning ready to be able to accept work.
