    Since it is all electric it has to be an outside source or as they said someone using some sort of heater. Kerosene does smell like diesel.
    Do any of your neighbors warm up a diesel vehicle outside?

    I'm not sure where you are coming from here. We do not know what the RH is so I don't understand how you can say "it is not too wet" and of course better insulating the ducts would prevent it.

    I'm assuming there is ductwork in the basement, if so you have return air leaks. They need to be sealed and a duct blaster test would confirm this.
