Hyde is also involved with an attempt to make the lightest Airstream trailer ever, hopefully less than 1,000 pounds. He has shortened a 1956 Caravanner from 22 feet to 11 feet, and put it on a new chassis and installed a new floor.

"I'm calling it a Mini," Hyde said.

He said it will have to have everything found in a larger model, but in a 9-foot by 7-foot body with room to sleep three. That includes a gaucho (couch) that pulls out to a queen-size bed, a hammock-style bunk, removable refrigerator, hot-water heater, shower, port-a-potty that will fit in the shower pan, sink and a two-burner stove.

When everything is stowed away, there should be enough room to store a motorcycle inside.

Vintage Airstream trailers are much lighter than today's models, Hyde said, which is important considering our ever increasing fuel prices. The largest Airstream model made in the 1950s, at 30 feet, weighs about the same as a 16-foot model built today.

Hyde said models from each era have pluses and minuses. He and his crew can put all the modern touches into a vintage trailer.

Some of those modern touches, such as solar panels, multiple storage batteries, LED lighting and grey tanks for wastewater help travelers to camp entirely off the grid.

United Solar Ovonic makes flexible solar panels that can be bonded to the roof of a trailer. Those will also be used on McConaughey's trailer.

Hyde said certain of today's generators can also run on propane, which can be used to power the larger appliances where no hook-ups are available.

GSM uses a combination of insulations. The interior wall is first covered Reflectix, outer layers of metal-coated mylar that sandwich a bubble wrap-type material that blocks up to 97 percent of radiant heat.

Hyde said he and his wife bought their first vintage Airstream in 2001. They now own seven, in varying stages of restoration.

"It's worthwhile to fix up something that's quality to begin with," he said.

The couple and their son travel extensively, racking up more than 10,000 miles last year and more than 6,000 so far this year. That includes winter camping, as the trailers are well insulated.

Hyde also takes part in a vintage airstream podcast, www.thevap.com. It's now heard in 22 countries, and gets about 5,000 downloads a month. He joins host Tim Shephard and co-panelist Rob Baker in discussions of various vintage Airstream topics, such as restoration, rallies, appliances, polishing and more.

Hyde will have his 1959 Airstream Ambassador International at the Vintage Trailer Jam, to be held July 11-14 at Saratoga Spa State Park in Saratoga Springs. The trailer still has a lot of original equipment, such as the curtains, counters and an Ogden Water Filter that contains a charcoal canister for use when traveling the world.
