Welcome back. And congrats on your C.
We'll be waiting for the pictures. :)
A Class C is like any other RV when it comes to storage.
The top of the list is a climate controlled garage. After that pole barns, carports, covers and tarps are used by many.
Some will tell you not to use a cover or tarp because it can rub the paint when it's windy.
Some will tell you there is no reason to cover or garage your RV because it's designed to be outside.
It all depends on how much you want to spend and what is allowed by your local municipality.
I would love to have a garage or carport. But, until I can build one, a cover is my choice.
