This slightly leading question/post from Mid-Century Style Magazine got me thinking. I have recently said out loud, "Let's get an Airstream, park it in the driveway and rent it to Austin tourists or use is as couch swapping bait" and "I think my next car is going to be a 60s Westy."
So to answer the question, yes. I think mid-century trailers, mid-century campers and probably mid-century cars are going to make a come back. But, as someone who writes a mid-century blog, I'm probably a little biased.
