Keeping DPF clean   MaxxForce 7 Issues

We started using cetane and it appears to help, we were occasionally getting the warning lights and they stopped flashing on. We usually notice a difference in acceleration power as the temperature rises in summer but so far no issues.

We also followed your suggestion about not leaving the engine idling but when i picked up the Vesta from the garage after having new carpet installed, the office had it running with the air going as a kindness for me.  Fortunately, we didn't have any issues on the way home.  

Thank you for your suggestions.

Glad you've had good experience with the engine management.  I've had no issues with mine and I continue to use Cetane and keep the idle to a minimum.

I've just finished a mod that might be of interest.  The slide room rides on 6 rollers that are only 4 inches wide.  I noticed that the rear roller had started to dig into the underside of the slide floor sheet metal ( viewed from underneath the slide while extended ).  

I've installed 6 sheetmetal "tracks" ( they are 6 inches wide ) for the rollers to ride on.  This will take a little pressure off of the schwintek mechanism and hopefully keep the rollers from digging into the underside of the slide floor.  

I found that the underside doesn't have much to secure the screws to.  I should have made them 7 inches wide and put the screws closer to the edge.  I'll have to wait to see how all this works with time.  I think this should have been an OEM standard install.  The rollers should be a little larger and have better bearings.
