Jayco boot handels

HI all picked up a new Jayco Penguin Out-back last November. Had made a few changers to inside of cupboards to strength up changed the wheels and fitted extra stone and mud protection but I expected these needed doing when I brought the camper. The problem I am having that was not expected is the handles on the front boot falling apart. They were both replaced last February at the first service after one fell apart and then one of the replacement set fell apart about two weeks ago. They were replaced by Jayco for free but I was told by the spare parts sales person that Jayco were having a lot of problems with these handles. I have now replaced them with the type that goes on shed doors. Has anybody else had the same problem and how did you sort it out? John C
