I am skeptical that a trailer can be sealed well enough to prevent
complete air changes due to pressure changes during say 6 mo of
storage.

Has anybody tried this?

From dealing with this problem on boats, I can virtually guarantee that sealing, or silica gel, will do little good. On a boat, I run a dehumidifier 24x7, as well sealed as I can get it (which is much better than a typical glider trailer) in a humid climate it will produce several liters of condensate per day. That will very quickly saturate any moisture absorbing materials you might use. Even if you close the trailer and tape all open seams (which might actually be possible on a PIK tube trailer) the initial load of moisture when you closed the door is considerable.
