Talk to almost any millennial who is traveling this summer, and you will hear them refer to "the Airbnb of" something. For every need once dominated by a corporate name, there are now sharing-based apps hawking rental cars, camping sites, RVs, swimming pools and more.
Like on Airbnb, there are inherent risks when you rely on private owners advertising their services on a third-party platform, and the reality of every excursion will vary. Still, the glut of options presents cheaper alternatives at a time when prices for gas, flights and other travel essentials are shooting up.
