You can find many of the online Jayco Manuals at http://parts.cunninghamcampers.com
, but they have not posted the 2010 JayFlight manual yet. I doubt there is much difference going from 2009 to 2010 manual - it has been pretty much the same for several years.
I have a pretty good library of manuals going (see my signature)....many of them were not my exact year (2009), but they dont seem to change much. Takes a lot of googling to find them all...
If you find a more up to date manual, please let me know and I will add it.
