DarbukaDave: Here's a mounting option you may want to consider since it fits very close to where you mounted your temporary suction cup. It clips into the seams of the dash and has the same AMPS hole pattern as several of the RAM ball bases. But I don't have any personal experience with it. I forgot about it until I saw it in my old browser history. I had decided against it because I wanted my mount further away from the dash.

The instruction sheet has closer pictures of how it mounts.

There's also one that mounts near the bottom of the air vent on the driver's side of the radio and another that attaches to the driver's side A pillar. Each of the mounts also has custom versions for both Gen 1 and Gen 2 Transit Connects.
