Hello Marvin,
Birch can be used on the exterior of a trailer, as can any commonly available species, heck, you could even use cardboard if you wanted...
It will have to be sealed very well...to the point NO moisture can penetrate from either side, the edges, or any fastening point.
Concrete sealer may help, but for all the effort involved, I believe I'd try to pinch pennies elsewhere.
Whatever sealer you use should be able to withstand UV and of course whatever type of weather it will be subjected to.

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
