I also bought a used Jayco that looked like new but since it was used and the warranty is non-transferrable, them's the breaks. Jayco is very up-front with their terms and conditions for the warranty and I made sure I was aware of that when I made the purchase.
If something does come up, I expect to take care of it on my own dime.
