How to protect roof top components under a cover

I live in the Northeast, and last winter we had 5 feet of snow. This is my first winter owning the r-pod, I bought a cover and am wondering if I should do something more to protect the roof top components. I plan to knock off the snow as it falls, but if we have a winter like the last one that may be hard to keep up with.

Thanks!

I suspect, based on all the people who own them not losing their minds in the spring, that TT roofs will handle the load ok.

Thanks everyone...I was concerned about the antenna, I was thinking of covering them with some type of box, maybe a plastic tote, but taking them off sounds much easier

My son ended up taking the entire antenna off the roof. He disconnected the cable inside the camper which allowed him to undo the bolts holding it on and take the entire antenna off. This left a small tube about 4" high, he covered that with a small plastic container. If anyone wants more detail on how to do this I can find out.
On another note, we had no trouble putting the cover on, he stood in the bed of his pickup (he's 6'4" which helps) and I held the other side as he pulled it over. He put the container on after the cover was on.
