First seeing production in the early 1950s, the Traveall was a long-running nameplate. But we are suckers for the giant-refrigerator-box-on-wheels look of the final version, which was made until Traveall production ceased in the mid-1970s. It's perfect for those times when you absolutely, positively have to carry everything you own with you.
