A couple of years ago, LDS apologist Scott Pierson (AKA Pacumeni) wrote a response to the frankly pathetic attempt by the Tanners to respond to the work of Warren Aston and other LDS scholars about the Arabian Peninsula geography of the Book of Mormon which remains rather informative since it was initially published in 2000:
Other cogent discussions of the Arabian Peninsula geography of the Book of Mormon, written in response to attempted responses by critics, would include:
Neal Rappleye and Stephen O. Smoot, Book of Mormon Minimalists and the NHM Inscriptions: A Response to Dan Vogel
For an excellent book-length discussion of the Arabian Peninsula geography, see Warren P. Aston, Lehi and Sariah in Arabia: The Old World Setting of the Book of Mormon (2015)
