Doesn't this winter weather get old? I'm ready for some REAL spring-like weather.
Regarding snow on your roof, I've yet to hear of anyone ever having a RV roof collapse because of the weight of snow. That tells me RV roofs are substantial enough to bear considerable weight especially when snow equally distributes weight over the entire roof, unlike when you walk on the roof and that weight is applied to the area of your feet only.
All said, however, I don't know the exact amount of weight an RV roof is capable of supporting. I'd worry more about getting up on the roof and falling off removing the snow.
