Check engine light came on again. They have no idea why now. Also steering is still bad. I really wish motorhomes has a lemon law clause cause I got one. It's going to cost me big ones to trade it off. But maybe more to keep it as it's not even three months old to me and the future looks bleak.

I think you mean the dpf soot sensor, I have a couple questions as this is what I do for a living.
1. What engine is it probably cummins.
2. Did you take it to a cummins dealer or back to rv center?
3. Did they do a parked or forced regen?
If they changed the soot sensor 3 times it is not the sensor itself and more likely a wiring issue.
If they didn't do a parked regen to clear the dpf of soot then all the sensor in the world wont fix it.
It would help a lot if you could give me the engine serial number and what the exact codes were sometimes the dash display will show codes with a spn### and fmi## numbers they are fault code indicators.
When doing a parked regen with a computer they can chart all the sensors in the exhaust system and tell exactly whats going on instead of just changing a sensor because that was the fault code.
Just because it had a fault code for soot sensor could just mean that the engine has another issue that is causing soot build up in the dpf, which mostly caused by a lot of low speed idling of the engine.
