Good choice, Ledges!
Did you still install it?
If not, check pictures, you will see how the Hidden Hitch is recessed under the floor.
Sorry if it's not clean.
Our hitch has been installed in 1998 and we use our RAV4 by winter and a lot of calcium is spreaded on road here.
So, a little paint job must be done on it.
