Excellent question because the one thing I was warned about is that how may people have destroyed a smoking caboose running with command control typical 18V on the track.

I'm not trying to tell you not to use the smoke unit, but you specifically said with your son. The last thing you want is something cooking off and melting.
Bottom line is, the stock system may have not been ideal, many people modified it or flat out switched to something entirely different.
