I have one and it allows me to reach the whole windshield, I have a special place for storing it, just be careful folding it they are finger pinchers and make sure that you get the correct size, there are at least 3 different models for different tire sizes, I only wash the wind shield at the end of the cleaning, that way I make sure that the unit goes back to its home, it is easy to forget and I always do the passenger side first and then the drivers side, that way it will be noticed if I want to open the door to move the RV.
They are worth it.
