I just want to say I have just been through this exact scenario. Percent off from Worldwide is almost exactly like Heyfly (previous post).
I have a 2017 Whitehawk that needs the j rail drip edge (gutter) at the corner of the roof. I called Jayco with vin (last 8 of serial number) and got the part number. I then called a Texas Jayco dealer who quoted me $84 for the 20' part. They said there was a $20 freight charge pushing the cost to over $100 (it comes in a roll).
I called Worldwide and they said the cost was $43 out the door with shipping. I was astounded. I made Garrett read the name of the part to me, with the part number to confirm no confusion. No problems with not using an exclusive freight carrier. So either I am getting OEM or there are serious discrepancies in costing out parts due to overhead at the dealers.
Either way, the part is on the way. Thanks Worldwide for opening up my eyes.
