ABS light
The anti-lock brake system light on my dash comes on occasionally and randomly. It doesn't come on every time I drive. It may not come on for hundreds of miles, like all the way from Sedona to Oregon...

If I recall, GM had some issues with sensors on front of pickups and SUVs (likely your motorhome if GM chassis). I want to say it was a bad ground or something similar on front sensor wiring? Perhaps look up TSB (technical service bulletins) for similar chassis looking for ABS problems?
