We use a Prestige cover on our Jayco Hawk.
It has straps with solid locking quick release buckles and straps for keeping the cover in place.
We have had our camper stored outside with strong wind and rain and the cover has worked very well.
Our Jayco is stored in a shed at the moment and the cover stops birds $hitting all over the camper.
I purchased it from our Jayco dealer for $140 after some haggling.
The ticket price they wanted over $200
