I’ve heard from a lot of people that have owned them that tear drops get old fast. They’re cool, but there are far more space efficient ultra lights these days, and you get a lot more out of a shell if you want to stay as miniature as possible. I hear a lot of nice things about modern hibrids, sort of small ultralight trailers that borrow from pop ups (which are cheap but awful.
If the truck is 4wd you can snag an outer beach permit and get in on those sweet beach campsites that aren’t open to tents or vehicles like the Vanagon. There’s a dry camping beach bum scene my parents are very into.
They lived at a campsite on a military base in Key West for about 5 months last year. All the same kit is apparently involved in off grid deserty camping out west as well.
We spent practically my whole childhood doing this kind if stuff all summer, every summer. Even the dogs loved it.
