Query: road trip helper

On a motorhome trip from Georgia to Alaska, I found it difficult to find replacement wiper blades for the older style wiper arms on our rig. We were unable to find wiper blades anywhere besides RV specialty stores at a premiim price. With these adapters I can grab a new wiper blade at almost any WalMart or parts store without paying too much.
