plocklin,

You've asked your question in a thread that has been "dead" since 2011. The OP was last on the forum in 2011 and the member who made the most recent response hasn't been on the forum since 2015. Additionally, there have been two recent (within 30 days) threads discussing operation of the furnace while towing. If you use the search feature and type in some simple phrases like "Operating furnace while towing" or "Towing with furnace" you'll find a number of responses.

Often it's more productive to start a new thread if you can't find the information you're seeking rather than to reopen a "dead thread" from years gone by, since many (maybe most) of the members who were posting in that "old thread" are no longer active on the forum.
