squeaky sliding door

[Lindakt2]

In our Roadtrek our sliding door squeaks at the rubber gasket when on the road. we have tried WD40 and a silicone spray which works only for a few miles.
Any ideas would be appreciated. Thanks. Journy3

Just a note: I wouldn't put WD-40 on door rubber. Overtime it may cause the rubber to breakdown.
I would use silicone spray on rubber.
