My 2012 Jayco Discovery is developing cracks in the front just above boot hinge and starting to run up to the joining strip above, they go down into the rubber where the closed boot lid sits. THe area where the boot lid hinge attaches to is where Jayco put a piece of timber and this rotted out 2 years ago and I replaced it with aluminium flat bar. Has anyone experienced this and how did you fix it. Thanks
