Some dry writings here about the Tabernacle, I do NOT recommend this book if u're looking at an 'exciting' approach to understanding the workings of the Tabernacle.
However, if you're looking for archaelogical, spiritual significances of the Tabernacle, you've hit on pure gold -- William Brown is probably the best yet at portraying a biblical design of the Tabernacle, as well as interpreting each equipment, the priestly services, garments, the offerings, the Tabernacle structure and so forth in the context of Jesus Christ, making the Tabernacle is distinctively CHRISTian, not a Jewish creation.
A friend of mine is basing his architecture dissertation on the Tabernacle and references to it often; also a book which Charles Spurgeon himself recommends. In the sixth edition (the newest one I believe?) there is an extra appendix on the distinctions of the Hebrew cubit (as it pops up many times in the OT) for those who are curious, as well as the distinction between Brown's biblical approach to the Tabernacle set-up, as opposed to heretical and unbiblical interpretations which were also around in the 19th century (as Brown was a 19th century writer).
