Travelling throughout the Eastern Seaboard in the 70’s, the first time I saw one my eyes bulged!  It still looks great 30 years later. So after the jump take a look at retrospective.  Afer all Evel Knievil owned one.

It’s Thunderbirds and The A-Team rolled into one, a low and sleek sportscoach that stunned the RV industry when it launched in late 1972. Today, exactly thirty years after production stopped, the GMC Motorhome is becoming a cult icon.

The GMC is the muscle car of the RV world. It holds the land speed record for motorhomes, clocking 106mph at Bonneville last year. It’s been immortalized several times as a Hot Wheels toy.

It’s even had a movie career, starring in the 1981 Bill Murray comedy Stripes. But for those of you who grew up in the 70s, the GMC will always be known as Captain America’s van.

That’s pretty remarkable for an RV that only had a six-year production run. But there are many, many remarkable things about the GMC. For starters, it was the first RV created and built by an automaker—and to this day, no other automaker has taken that risk.

GM called the project TVS-4 (‘Travel Vehicle Streamlined, model 4’). For maximum grunt, it dropped in a mighty 455ci V8—the engine that powered the 1966 Toronado. A claimed 260 horses were fed through a three-speed gearbox to the front wheels; with no driveshaft running to the back axle, this gave the living area an extra-low floor and lots of headroom. GMC looked sharp from the start, sitting low on its haunches. But the front wheel drive gave traction problems on uphill grades, especially in heavy rain or snow. Handling was otherwise decent, helped by a low center of gravity and an air spring setup for the four wheels at the back.

You got the choice of a six-berth 26-foot or a (relatively rare) four-berth 23-foot. The sleek styling gave an amazingly low drag coefficient of 0.39. And the interior was funky even by 70s standards, designed with the help of House and Garden magazine. The wraparound glass looked cool, but in hot weather the large windows put a huge strain on the roof-mounted air conditioner.

At launch, the GMC cost between $12,000 and $16,000. And what a launch it was: the stock prices of all the other major RV manufacturers fell the very next day. Their vehicles suddenly looked very old. As the GMC sales brochure said, you could now buy a “motorhome that doesn’t look like a box or ride like a truck.”

GM originally pitched its motorhome as a ‘multi-purpose vehicle’ for extended living. That was mostly a marketing fantasy, but in 1975 GM did launch an unfurnished Transmode model. Soon, GMCs were being turned into everything from mobile recording studios to laboratories. The Transmode shells were farmed to conventional coachbuilders such as Coachmen, and even Coca-Cola got into the game, offering custom ‘Gadabout’ models as prizes.

And then, suddenly, the wheels came off the bus. The fuel crisis played a part: the GMC’s 8 to 10 mpg thirst was actually pretty good for a Class A with a big V8, but the running costs became too much for the American middle classes.

In 1977 GM shrank the engine to 403 cubes, but the sticker price had already soared to $38,000. There was no place for the world’s coolest RV any more: in 1978, the production line in Pontiac, Michigan was shut down.

Some 13,000 GMCs were made in all, and many are still on the road today. Winnebago released a thinly-veiled copy in the late 80s called the Spectrum 2000, and small numbers of other GMC replicas have been produced by companies such as Silver Motor Coach.

Today, thirty years on, the originals are relatively easy to keep on the road. Rebuilt engines are available for $3,000 or thereabouts, and the bodies are made from long-lasting aluminum and fiberglass.

Some owners restore their GMCs to showroom condition, while others update the interiors in superyacht or Airstream CCD style. The only real bugbear is the underlying frame—which could cost up to $10,000 to fix if decayed. But a thriving restoration industry makes it easy to keep the mechanicals in good running order, led by specialists such as Cooperative Motor Works.

GM itself briefly raised hopes for a Mk II Motorhome with the award-winning GMC Pad design concept in 2005 (pictures below). But nothing more has been heard of this. The future of modern RV design probably lies more in the direction of VW’s acclaimed 2001 Microbus Concept.

There are plenty of GMC links to stoke your appetite, from Flickr sets to extensive histories. The best GMC fansite of all is probably bdub, with its archive of GMC brochure eyecandy and a thorough GMC FAQ for newbies. If you’re hankering after a GMC for yourself, keep an eye on eBay or the big RV classifieds such as

Just remember to set aside $20,000 on top of the purchase price, and then you can create a personalized RV that looks like it’s just rolled off the set of The Jetsons. A much better—and cheaper—proposition than a 40-foot white box with cheesy graphics.
