Jane,
If you still have the factory senders, there is very high chance that they have failed. The original construction of the senders was that water could get into the variable resistors and they fail. They are not repairable and not available, but there are several fixes that you can use.
A new style dry electronic sensors are available that are a direct bolt in and wiring.

and

I did it this way and they work well.
Now a more cost effective route is to use this:

I have this in our coach now and it does work fine. They are a probe unit and does require adding probes to the tanks and some wiring.

I think Chuck has a Coachman, so there mist be paper stuck on the sensor.
Fill the tank about 1/3 full and jerk as you drive as the water need to
slosh on the rear side.

Chuck,
I can get you new style sensor screws that tends to over come that issue.
