Volks, I really have no idea of just how much "hot water" you masochists
need while jaunting around in your Westies during the Winter months,
but, as a veterinarian, I have some more affluent colleagues who have
BOWIE veterinary bodies in/on their pickup trucks which make performing
large animal calls MUCH nicer!  The Bowie website is
http://www.bowiemfg.com/ and their inserts offer 13 gallon hot & 13
gallon cold tanks.

I talked to two of my colleagues who have these units, but neither
really could tell me just who manufactures the heating units within the
Bowie units.  They do involve splicing into the cooling system, though.
As you probably can figure, veterinarians are quite particular about
"things" working properly.  One might consider checking with Bowie to
find out just who that get the water heating unit from.

Also, for those who really desire to have vast amounts of hot water,
there are natural/LP gas "demand" units available.  When I remodeled the
restaurant I bought into a veterinary clinic, I investigated those small
gas-fired hot water units to use at each sink/tub site.  Decided since a
60 gallon gas-fired water heater was so cheap, I'd go with it.  One
might check into installing one such unit in their Westy for hot water
"on demand".
