Lake Louise trailer park or Icefield parking lot.

If you look at Tunnel Mountain Trailer Court in Banff you will find that the way they have it set up is so the RVs are end to end rather than side by side. Basically parallel parking from the access roads.
There are many individual sites for bigger RVs but also a lot where 2 units are end to end, but share the same pedestal for hookups.
I have stayed there many times, it is actually quite nice.
You get the feeling of distance from your neighbor because you are not looking out the window at their site.
