LOL....
People RV for a lot of great reasons.
Mostly (90%?), people RV for short, fun vacations and getaways with family/friends (and their RVs sit in storage 340 days per year)
Some people use their RVs more often for fun (...these are the lucky ones!)
Some people use RVs for temporary housing during home remodels/etc.
Some people use RVs to live in because they cannot afford renting an apartment/home.
Some people live in RVs full time because they want the freedom to travel anywhere in the country.
I'm guessing 0.0001% of people RV "to use less electricity" and to "save the planet". Do you think the author of that article knows this? Probable. Fun to read anyways.
