Don't know if everyone knows but Jayco will send you the drawings and schematics for your unit if you provide them the VIN and all of your contact information. These come as pdf files and have been free in all of my contacts.
You need to Fill out this Form
at the Jayco site.
This will only work for a unit that is 'out of warranty'
is very important since instructions that followed my 6 files were:
"Print 21.737 use page 19 of 39 Doorside Print 21.742 use page 8 of 21 Off-door side Print 22.012 page 4 of 9 rear wall Prints 22.335 use page 11 of 20 and print 22.025 use page 3 of 5"
You can see that out of 94 drawings I will use 5 of them for my unit. The sixth file included all of my 12V, 120V, Black, Grey, and FW systems.
I did not request the roof framing but may do that in the future. Be specific on what you want as they only give you what you ask for.
My request was filled in 18 hours so the service department was very responsive.
Great service from a customer focused company.
