Just my two cents, but the book Wilson's quarter century in photography is free on Google books, and includes recipes and such for wet and dry plates.
Also, wet plates have a time limit on on how long you can use them. If you can bring a plate coating darkroom with you, wet plate may be fine. If you can't bring a portable darkroom, dry plate may be your only option.
