I came across an interesting site recently while doing some Revcon research. You all know that the Revcon had a place with state and local governments, many were sold for command posts, communications vehicles, and what not over the 1980's. Well, come to find out a little organization called the "White House Communications Agency", through the GSA purchased six 34-foot coaches in the 1982-1983 time period for use in supporting remote Presidential communications. These were called "Coaches" by the WHCA, were loaded with communications equipment, and were used until the mid 1990's.
For a good read take a look at this article...
