We use the ADCO covers for both our TC and our Airstream...have used them for many years.
They are a significant help in keeping them clean.
The TC takes about 5 min to cover...stand on the roof and pull it over the front.
The Airstream takes a bit longer...maybe 1/2 hr, as I need a ladder.
We only use them when we won't be using the camper for a while, like right now. The TC will be covered Nov-Jan, then in Feb I will uncover and start using the TC for skiing. The AS stays covered Nov-June...we only use the AS in the summer.
Best option would be a pole barn/carport...our backyard is sheltered from wind, but does have a LOT of trees. So the covers are great for sap, dirt, etc.
One of these days I will build a bigger barn to fit everything inside...for now, the covers are fine.
