I think a bit over sized isn't good. In the case
of my drafty trailer, I can always light a couple
stove burners if the furnace isn't keeping up.

Works out, OK. I went from 80k to 70k when I replaced,
and the 70k does fine. Of course, some cellulose in the
ceiling helps, a lot.
That's still almost TWICE the size of the furnace in my 2 stoey
house in Ontario.

Your house is a *tiny* two-story (very little ceiling square footage).
It's more like a small townhouse. Of course it has an apartment-sized
furnace.
