Not sure if you mean with a camper trailer or not.
If you are then we were in the high country on the first day of summer a couple of years ago and had about 2 inches of snow overnight. It was lovely and basically disappeared by lunch time the next day.
A couple of things I learnt from the experience are:
- Snow is very quiet and you don't know it's happening.
- Some pr*ck doesn't sneak in and steal your mat outside the camper during the night, it is actually under the snow. (Getting up for a pee in the wee hours without brain fully functioning.)
- Snow is heavy and you need to get it off the camper as it starts to stress the bows and guy ropes.
- Snow is not that easy to get off the trailer, particularly when it is still coming down, it's dark, and you only dashed out to pee and didn't rug up.
- Snow seems to keep the camper warm.
- We were lucky and there was no wind so wasn't that cold, but with some wind it would have been bitter.
- There is no way we would purposely camp, in a trailer, in the snow for more than a night.
This is the camper mid morning with still about an inch off snow on some of it.
