If the dry box is big enough ,it's better to put camera body together.Use the plastic cap for lens too.If got extra cash buy a dry cabinet
as it will control humidity in the cab to keep equipment fungus free. For the time being if you have silica gel sachets put them in dry box,it will absorb moisture in the box.Do not use "hungry hippos" descicants meant for rooms or clothing cabs ,may spill water.
