Using an RV Cover

Don't worry about roof vents, but cover any sharp points. I use foam pipe insulation, others ode pool noodles. Don't forget about sharp points on the sides as well. When you put the cover on, make it snug enough to prevent it from flapping around, but not too tight. My cover is several years old and is showing no signs of wear.

There's no need to do much of anything before installing the cover other than padding any sharp corners that could tear the cover. I use foam pipe wrap over the spout extensions and wrap any sharp body corners & the ends of the awning with pieces of Reflectix, securing each piece in place with clear Duct tape which removes easily in the spring. The radio antenna I simply fold down out of the way, my Winegard TV antenna I don't bother with but if you're concerned just cover it as well with padding. I've been doing this for 10 years now with 3 different trailers, no issues at all. :B
