Hypoxia - thanks for the link. My control pad works slightly differently. I found the instructions for overriding the control panel. I tried to force into Travel Height, but it wouldn't work since it is not communicating with the rear. I can force the front, but nothing at the rear.
Encantotom - that's very true! Valid has said they can talk an RV tech through some troubleshooting if they can get to the sensor. I may have to try myself, but my age and arthritic knees make it tough. I have lifted it enough to be able to see the connecting rod and sensor arm at the front of the wheel well, but not sure I can get to the actual sensor. I know Valid works with Spartan chassis, so I wonder if any Spartan techs would be able to help...
