Like my brother's 35-foot "diesel pusher," complete with 8-kw Onan
diesel genny under the front and IIRC roughly 1,000 lb of batteries.

Me too -- though I believe all those old Servels have been recalled
for excessive CO output.  We had that in my Grandma's cottage on
Winnepesaukee long before we stopped cooking on kerosene wick-burners
with a trough and a bubbler full of kerosene on one end.  Never gave
a bit of trouble that I was aware of, though I'm pretty sure the
small freezer never got anywhere near zero F.

Within their limits, yes.  They're very inefficient compared to
mechanical refrigerators, but that's more than made up by the truly
horrendous energy density of commonly available batteries.
