I cannot answer the technical aspects of your questions, but I can offer
some reasurance.

In Winnipeg, almost all the taxicabs (large modern American sedans) are run
on propane. I think they can operate on dual-fuel, too.

They have a propane tank in the trunk - it butts right up to the back seat -
and no-way does it occupy the greater volume of the space.

You must go to certified places that do the conversion for you - tt's not
something the Propane Police allow the backyard-ballistics guys to do
themselves.
