Unlike open flame propane appliances, carbon monoxide is not the main safety issue with cat heaters.

EDIT: And I'd go with the Propex. You've already got propane on the trailer and can probably find a way to permanently install the Propex. Only problem is I dunno if it'll be enough BTU at 0F temps...might have to get two of them.
