Ah, different environment, different experiences, I guess.
I know of one RV in the entire western suburbs here (I’m sure there are more), but local bylaws limit where they can be parked and for how long (ie, not year-round). I’ll concede that supplying juice to an RV never occurred to me. So as to the super-vague wording, I’m willing to bet that in context, the NFPA anticipates millions of EVSEs to be installed in the near term, but little growth in the driveway-bound RV or home welding markets.
