Due to the general slide in retail fuel prices, diesel is now under $3.00/gal. here for the first time in a very long time. Kerosene? $3.99. Not moved much at all.

Is there any reason they can't burn highway diesel in their kerosene heaters?

I don’t use them so I can’t say, but the two are quite similar to the point of being interchangeable in diesel engines. Don’t know about effluent and enclosed spaces, though.

yes heaters require k1 kerosese.
