Whistler is a beautiful place to camp. I couldn't get hookups while I was there, but the weather was cool enough that opening the windows
and running the 12v fan kept the trailer comfortably cool. I even had to turn the furnace
on a couple if mornings because my significant other felt that it was a bit too chilly. I suppose it depends on the length of your stay. If you can get by using propane
and 12v appliances/lights for a few days, even the big 5ers should be OK.
