auxiliary heat

I'm assuming you mean for seat heat, and not space heat? It's awfully
difficult to get much heat out of 14V. Even automotive folks (with a fairly sealed
cabin) do very minimal heating on very localized areas (read: arse). It might be
doable, but only for localized/concentrated situations (seat heat, blankets, etc).

Imagine getting cabin heat from a hair dryer... 1250-1500W... around 100A for
14v.

Correct.
It would be about like huddling around a 150 watt lightbulb. I'm thinking
heated seats or blankets.

There are motorcycle vests that really work. They use the motorcycle
battery so they don't draw "much", though I really don't know how
much. It's like having the sun beating down on your back. Work best
worn under a jacket. Check out moto cycle shop or online motorcycle
supply place.

Also have a look at electric socks. I find it's very true that when
your feet are warm, the rest of you feels warmer too. A down-filled
sleeping bag (unzipped wide-open) makes a nice warm blanket for your
back seat pax to cover up with too, and doesn't have any electric
requirements. That's what we used last winter and it was very
effective. Not very "elegant" but it got the job done.
