I also have these door handles with locks installed on my RV-10, and I am happy with them.
On installation, I had a problem of my own making. I tried to install the plane-around 180 latch at the same time as these handles with the standard Vans pieces. The problem was that I changed the standard distances internal to the door in order to center the handle mechanism in the door pocket. This caused the Plane-around actuation "bars" to be the wrong length, and required custom made replacement to make everything fit.
If you already have the standard Vans handle in the standard location, then installing these new handles with locks should be simple.
