Look at it this way, a 200 lb man walking on the roof with the weight concentrated in small areas (footprints) vs weight of snow spread out over large area. The roof can handle a lot of weight if it is evenly distributed (snow). Bigger concern is your AC, when the snow starts to melt the snow will act as a dam and direct water into your coach (not good). Put a good quality cover over your AC, use a broom and remove the snow while you’re up there, sit back and dream of warmer weather!!!
