The Toyota Land Cruiser Association is probably the best vehicle-specific organization you could possibly join.
And yes, they are
more than "hip" to the FJ Cruiser. Matter of fact the FJC has become a common staple at TLCA events and feature articles within in the TLCA magazine (
"Toyota Trails").
Many FJ Cruiser owners are also current (or former) FJ25, FJ40, FJ60, FJ80 and FJ100 Land Cruiser owners. And, you'll find a large number of members of this great Forum who are not only TLCA members, but also writers/contributors to the TLCA magazine.
