Since we rarely have full hookups, and the work appears to be getting to the tank, I went a head and order the SeeLevel II. It is $140 more than the Horst Miracle Probes. There is just two wires that go between all the probes, so wiring should be that bad, just getting to the tanks.
Here is what I ordered.

Just need some good weather, and I will let you know how they turn out.
