To obtain 3rd party part number (instead of Jayco's part number), you might want to contact folks @
http://www.campingworld.com/ as well. Simply call them or send them an email. Or if a store in your region, visit their large parts store. And when part number is known, you can also compare their selling (install) prices.
If your current RV salesrep cannot help, then perhaps other RV dealers (parts stores) in your area can help as well. Luckily, I have 2 RV dealers within my area. And, each has different selling prices on the exact same item. Thus, it saves to shop around as well...
Hope this helps...
