ok...here is an update. I think I have the plan.
The quick connect fittings on your Jayco Eagle are non-standard. They are proprietary for RV LP use only. As such, the fittings can only be found at a limited number of places online. They are not available at HW stores, or even Gas and Grill stores.
I was able to find them at Recreation Nation: https://recreationnation.me/main
Here is what I ordered:
For the "T" adapter to turn my single LP Quick Connect port into a dual port:
2 female quick connect fittings: https://recreationnation.me/main/con...ut-14fpt-inlet
1 maile quick connect fitting: https://recreationnation.me/main/node/3426
1 Brass "T" fitting: http://www.quadratec.com/products/92042_9131.htm
I also purchased an 8 foot hose with one end male, and one end female to connect the "T" adapter to my grill. I will use the OEM hose to connect the 'T' adapter to my stove.
I will let you know how it goes!
