The other day, I e-mailed Jayco, asking them for the blueprints for plumbing, electric, and framing. That was on April 26th. I received a response yesterday, with the electric (both 120v, and 12v), and plumbing diagrams. The framing one had been purged from their system. Our TT is a 2012, so if anyone is thinking of asking for some, keep in mind the age of the unit may be too old to get them all. Kudos, and thanks to Kevin Stahly at Jayco customer service for digging out what he had available. They REALLY do try hard to keep us happy.
