Hi, sorry I was a little late on the reply, but this is a good place to start...
As stated, they have alot of products, so you'll have to make sure your in the correct area. I haven't tried it, but you may be able to call them and get technical assistance also.
Also, I don't think Jayco's quality control is at fault on this one, I'm guessing they just get the rolling chassis from Lippert or whoever and build the trailer on top of it, so I'm not sure they even check that stuff. I agree it's still not good to put that out in their dealerships, maybe in the future they will start looking at the chassis also.
