I personally was interested in fleet side 4x4 crewcabs , however it sounds like there is all kinds of interesting info in that book. What's the name of the publication ?
I got to looking closer, the book isn't all that hot for total #'s and it doesn't list R/V series in 1990 like it does in 1989. The book does have some really nice color photo's and I have read it cover to cover a couple of times, mostly looking at the pictures and gleaning over each years changes...
