I think the OP wanted a storage shelf not a full time job flipping boards.
You're right on tract with the pessimism, next will be the 25pgs of guesses and inaccurate assurances.

Here is a way to eliminate sagging and not have to keep unloading your shelves and flipping the boards over until they reach Snoonyb's level of dryness.
Take a 2x4 and cut it to fit between the unistrut. Screw it to one of the 2x6's (after flipping it) to form an L shape. Do this to several of the 2x6's and lay them out 16" (or possibly 24" OC). Lay your plywood across the top of the 2x6/2x4 combos and screw it down. You won't lose any headroom as the 2x4 wouldn't go below the unistrut level and wouldn't raise the level higher than it is today. The 2x6's are laying on their weak axis, adding a perpendicular 2x4 will strengthen the structure and prevent sagging.
In reviewing the pictures he has the room for a 2x4 installed vertically and flush with the top of the unistrut.
The 2x10's will continue to sag as he flips them over for several years until they reach the level of dryness you are looking for.
So, 1-5/8" unistrut + 1-1/2" 2X10, equals the width of an 3-1/2" 2X?????
Well, why didn't you say you were the OP's neighbor and reside in a dwelling identical to his with the same sun orientation and simultaneously activated garage door openers, and you verify with each other before entering the garage through the pedestrian door, so you have the ability to perfectly access the rate of drying of wood members.
