Do not buy the Camco Brand. I have lost 2...one after the first year and the second one lasted 2 1/2 years. Both of them cracked where attached to the mounting bolts and simply blew off. One while going down the hiway and the other while camped in windy conditions.
I will next try Maxair Brand. I had that on my old RV and lasted until the day I traded it off.
