RV = recreational vehicle, like a travel trailer, motor home, or conversion van.
RV'er = a person who is an RV enthusiast, more or less, whether by choice or necessity.
Boondocking = overnight parking without campground facilities. Ex: We often boondock at Wal-Marts when we travel.
While I usually have as little to do with Wal-Mart as possible, when we travel and need a place to park the travel trailer over night, we'll pull right into a Wal-Mart because *it is allowed!* The Supercenters have an unwritten policy of allowing overnight RV parking, thus making the centers enormously popular with RV'ers.
Start looking around at night if you go to a Wal-Mart Supercenter. You will probably see some RV's around the distant perimeter of the parking lot, sometimes there will be A LOT of RV's out there.
While many will be travelers, more and more people are now living in their RV's. This video is a humorous ode to that.
Watch closely for subtle humor. I like the employee and bottle of wine scene.
