We have a 1984 34 foot 3-axle Airstream (named Stretch) purchased at Can-Am RV near London Ontario in 1996. They have set up 2 tow vehicles for me so far ('92 1500
Suburban, and '97 1500
Suburban) I've towed Stretch about 30,000 kms with these 2 vehicles including the prairies and Rocky mountains. At 300,000 kms the '97 the tranny died. Not a bad life though.
We traveled from London Ontario to Los Angeles in the year 2000 with 7 kids, oldest age 11. We didn't anticipate how much work it would be but still have tons of great memories and photos. (Mt. Rushmore, Grand Canyon, etc) The 3-axle, narrow body, towed like a dream everywhere. Again, the combination was set up at Can-Am Rv, they had me use 8-inch rims and a shorter profile tire on the '92 Suburban.
For the '97 suburban we acquired a Hensley hitch and stayed with the stock rims with LT tires.
I felt that I had sufficient power and great handling with both suburbans (5.7 litre).
Stretch is a rear twin, with aluminum framed removable canvas bunks above the twins. We even had a 3rd aluminum framed bunk crosswise above the rear window above the foot end of the bunks made for us, again at Can-Am. My 13 and 19 year old boys still prefer the bunks!
Stretch is not as shiny as most Airstreams but sure has lots of experience and stories. We're planning a trip to Montreal and PEI this summer, with 2 adults and 2 teenagers now.
