A cover is a cover no matter what kind of RV. So in this, we all share the common experience.
You need to ask yourself (first), Why do you want to cover your RV? What purpose will it serve?
If you don't have a solid, valid answer, then covering is a waste of money and time.
If you are covering to protect it from something, like dropping from trees and birds because the RV has to be stored under trees, it's beneficial to cover.
If you care covering to protect from intense sun, like in South Florida or Southern Texas, it makes sense to cover.
But to cover, just for the sake of covering, is a waste of time and money. No, you do not need to cover.
Next question you need to answer: Are you young enough, flexible, and fearless enough to wrangle a cover over your coach and be able to do it without ending up in the hospital? If you've reached the age in life where every step is carefully taken because it may result in a broken hip or something else ... well ... covering is simply not worth it.
If YOU can answer those two questions, then you have your own answer.
Good luck!
I do suggest keeping the tires covered as much as possible. This does not hurt anything and it's kind of hard to fall when your sitting on your bottom on the ground to put the covers on! ;)
