Debate on transferring load to or from trailer at sandy creek crossings

We are having an interesting discussion at work. Light hearted but real enough

When towing a trailer, and when confronted with a deep sandy creek crossing (Nolan's Brook or similar), in addition to the tarp, lowering tire pressures on both the car and the trailer, do you move easy-to-move weight (heavy crates containing camp oven etc.)
A) from the trailer to the car, to give the driving wheels more weight than the towed wheels, or
B) from the car to the trailer, to spread the load more evenly over the three axles

Personally I believe the trailer should be as light as possible, to have as little drag as possible, and could then easily be off-hooked in case you have to and easier to retrieve if you had to unhook to save the car.

But I can also see my mate's viewpoint - spread the load, if you unhook you get rid of a proper third of the weight and the car is easier to get unbogged and removed from the water.

What do the forum think?

Cheers,

(PS Yeah I know not to do it without and without others present, and yeah I know the 'why risk it' questions are valid, but those are not the points of this discussion)
