With the right sized drill bits in hand, I was able to continue on the door handle assemble.
The instructions are fairly straight forward, but the whole process seems to take a lot more time than it should, and there is a lot of work to get everything fitting just the way it should for smooth operation.
I am also using the PlaneAround 3rd door latch system. This setup uses a cam in the center of the door to help pull the door in tightly as the normal door pins engage. This kit also comes with the parts to allow the handle to rotate a full 180 degrees during the open/close process, instead of the standard 90 degrees. This extra movement allows you to set the timing in the handle mechanism to allow the cam to start pulling the door in before the pins extend into the door frames. When set up correctly, it should be almost impossible to close the doors incorrectly, and provides a nice tight seal.
Sean from PlaneAround provides excellent instructions with pictures, but the installation is a pretty detailed process with a lot of careful measurement, and some of the PlaneAround instructions require you to NOT do some of the things Van’s tells you to do with the stock setup, so it was important to really read thru the directions and understand how everything fits together before diving in.
And finally, I got the handle blocks match drilled to the doors themselves.
