Produced in the 1970s yet looking thoroughly modern even today, the GMC motorhome is a much sought after vehicle by collectors. It’s smooth and pleasing lines, its functionality and innovate features make it stand out amongst its contemporaries. It’s a real head turner and futuristic in every aspect!
Introduced in 1973 this is an early example of an integrated motorhome. At the time when most were bodies built on bare truck chassis this one was purpose built, conceived from the ground up to address the serious shortcomings of the models being offered at the time. With that fresh slate approach in mind the designers could really innovate and they certainly took advantage of that.
Its looks alone meant it would stand out. While other motorhomes of the era were boxy and angular, this one had soft and smooth flowing lines and instead of ugly square windows those on the GMC were expansive and blended seamlessly into the body. Almost egg shaped, in some ways it reminds me of the little Boler trailer, many of which can be seen on our site. (Boler!)
An example of how innovate the design was can be seen by looking at the drive train. It’s front wheel drive and this allowed for a very low slung floor since there were no drive shafts running the length of the body. This low profile also made the vehicle quite stable and you often hear how well they handle on the road, almost car like. Amazing given its size. Power was supplied by an Oldsmobile gas engine.
Another interesting feature were the rear wheels – there were four of them in a side by side layout rather than dual wheels on a single rear axle seen on other motorhomes of the era. This not only provided a smooth ride and excellent braking it also added to the futuristic look. By not using axles this also meant more cabin space and the each pair of wheels was a compact assembly attached directly to the chassis. These bogies included a levelling system using air bags.
Other advanced and uncommon features, for the time at least, include air conditioning (the centre pod on the roof) and cruise control.
Overall this was a very advanced vehicle and way ahead of it’s times and while it was good success, not a huge one, its cool features probably had other motorhome makers scrambling to produce something that would stand out as well.
Some 13000 were made during the span of 1973-1978 and according to sources at least 8000 or more still exist to this day. That’s a real testament to the quality of the design – the youngest are over 30 years old! I understand many of those out there have been rebuilt and renovated and are as solid now as the day they were built.
These motorhomes, interiors and all, were made in-house by GMC at Pontiac Michigan. Some however were shipped as empty shells to be completed by customizers.
This example was seen in High River Alberta appears to be in good shape and had a for sale sign on it. If you like this motorhome another interesting RV is the big pink trailer.
Update: May 2013. We found another one on a recent trip to Drumheller Alberta and we’ve posted a picture of it at the bottom of this article.
