We moved to a tiny house in 2015 and got rid of the tent, portable toilet, and other camping gear. I thought we were done with primitive camping until I was inspired by the videos below.
Tried it out this past week (1 private campground and 2 national park campgrounds) and it has more benefits than costs! Little setup or tear-down. Bad weather like snow doesn't collapse the tent or freeze us all night long. Prius acts like a power generator. Music in the car does not affect the neighbors. Inspires others to think outside the box. Can arrive at your site later and can leave at checkout. And no worries like you have with an RV (fuel costs, tricky roads, grey water).
