Electric Tow Vehicles - Getting close

I think its a big concern right now.  take the Banff national park for example, now try to book a weekend, any weekend a day or two after it opens for the season, you might get lucky but chances are you won't.  Two years ago I was in the que for the opening day of the reservation site for the season, I was 175th in que as I was up and called in very fast, by the time I got up to my turn there were no sites available for the whole season  so over 1000 sites in the park were booked solid from may to end of September by 174 people.  personally I think a lot were companies and such doing mass bookings which shouldn't be allowed but hey.  

so now why do I mention this, tenting sites are non reservable, for the most part, and there are tones of sites just for tenting in the park, probably close to what there is for rv's  so its not a small community.  now if they start getting in on the bookings for rv power sites that's going to conject a system that is already overloaded due to tourism and such and then spread out to provincial and state parks.  I know I have been seeing it once and a while, but it is becoming more common to see a tent site with a tesla or kia plugged in to the 120V plug.
