Internet Idiot’s Guide for GMC MotorHome Information

This Guide is designed for the internet-savvy GMC MotorHome or TransMode owner or enthusiast. Formerly available only as a PDF from the website of GMC Eastern States Motorhome Club, the document has been reformatted for distribution to iPad owners.


For those who aren't familiar with the subject, GMC designed, built and completed motorhome units from 1973 to 1978. It featured the Oldsmobile 455 cu. in. engine with front wheel drive based on the Toronado that was already in production. GMC's units went by the product name of MotorHome. Units without complete interiors were produced as the TransMode. Other builders received these coaches and made them into motorhomes as well as other types of commercial vehicles such as mobile offices and people haulers for use by car rental agencies or feeder bus lines. The GMC MotorHome was known for it's futuristic construction techniques and timeless design. Thousands of units are still licensed and on the road today.


Use this guide as a handy reference for web-based information regarding all facets of the GMC motorhome community. In addition to chapters covering the history of the product, there are divisions dealing with other aspects of maintenance or enhancement as well as social and technical motorhome clubs. As with the original document by Gary Bovee, the section of service and repair facilities is continued as well as the extensive list of vendors that continue to support the GMC motorhome community with innovative products and services for their vehicles. New to this iBooks format is a chapter about rebuilding the 455 or 403 engine as well as information about “Dr. Oldsmobile”, Joe Mondello, who was well known for his methods of enhancing the basic engine for maximum performance and durability.


Following in the path of the original format, several of Byron Songer’s illustrations accompany the text making the publication look as crisp as possible. Both Bovee and Songer are committed to providing accurate and helpful information for the owners of these classic vehicles known for riding more like a car than like a truck.
