Welcome to our Trivia page!


Did you know..?

The X80300 option, on the Service Parts decal, is the GVW identity. Like most "options", the last 3 digits change by year, i.e., 1975s are X80500, 1978s are X80800. Sometimes the options show as 801, or 802. In later 1973, when the GVW went to 11,200, they changed to X80400.

Definitions ---

GMC Motorhome: a self-propelled vehicle with chassis and body manufactured and assembled by GMC with a serial number beginning with the letters "TZE". This term is used to refer generically to the vehicle regardless of the upfitter and purpose (recreational vehicle, people mover, ambulance, etc.)

GMC Motor Home: This is the product name designating a vehicle completed totally by GMC, including the interior. These were purpose-built to include kitchen and bath facilities in a self-contained coach. Units completed by another manufacturer or upfitter, such as Coachmen or Navion, did not go by this product name, but would go by the name listed below or the one mentioned above.

GMC Transmode: This is the product name designating a vehicle whose chassis and body were produced in the GMC plant but delivered to another upfitter who completed the coach. For instance, some were completed as people movers and used by Hertz to transport customers from airport terminals to rental car lots. Some units were sold to government agencies and used as mobile labs. Still others were delivered and finished out with interiors for use as motor homes. In other words, a Transmode could have seen service as a motor home or as a special purpose vehicle without living facilities installed.

Service Parts Identification Label

If the motor home was furnished with a GMC interior, the label in the glovebox identifies the interior finish model, except for '73 & '74 models.

Elegant Coach of Minnesota

9010 Pillsbury Ave, Bloomington, MN

While we don't know how many Transmodes Elegant Coach upfitted, there is only one listed in the GMC Registry. What is interesting about the Elegant approach was the interior layout and choice of materials.

For example, there was a toilet, but no shower. There was a huge entertainment center making a focal point, a leather-look ceiling, a hot plate instead of a stove and a wet bar, double facing couches in tan leather and lots of interior lighting controlled by a panel on the wall.

The most noticeable exterior feature was the raised, brass wings about 2' wide with a red ball in the center. The body was painted an off white with a red stripe.

The single Registry listing was last spotted on a car dealer's lot in Canton, NY in 1998. (Update: the coach was spotted again in May 2009, same place)
