Just some questions. I would be interested in your thoughts, ideas on extension mirrors. Do you use them? What brands do you have? I know some states require them while towing. I bought a pair from Curt Mfg. They are held on with rubber straps which deteriorate very quickly. When I complained to Curt they very nicely sent a second set of straps (They claimed that the new straps were of a better material.) but the new straps have deteriorated too. Thanks.
