I discovered on our previous 16.49 HL that whilst the lid closes on a back sloping angle, the catch strike plates were attached to a slightly forward sloping body moulding resulting in the strike plates angled against the lid rubber seal. To accentuate that issue the strike plates as also mounted proud of the body moulding sealing surface. The rubber seal was completely sliced through where the strike plate contacts the seal made worse by the increased pressure of the plate being mounted forward. The lid seal is not so much being held and sealed against the body moulding, and is more just being compressed onto the two small areas of the forward mounted strike plates, proud of the sealing face f the boy moulding. The effective sealing of the rest of the rubber seal would be more be more luck than design.
On the 16.49 I had the seal replaced at the Jayco factory, with the assertion they had never seen that before. Impossible me thinks, and when I collected the van to their credit they'd checked every van that came in, and found every van affected. They replaced my seal, but did nothing to fix the issues, which have virtually immediately repeated itself. That was 2009. 5 years, and many model updates later, nothings changed. A simple fix is to bend the strike plate to the lid slope, and mount the plates in the correct position in line with the body moulding, both of which was beyond Jaycos care level, or brain function. Another free, ridiculously simple and arrogant dismissal that plagues Jayco's reputation of quality control (or complete lack of). Its difficult to have quality control, when your design is $hit, and you know its $hit, you dont fix it and you dont care. Whoops, Im digressing
Our 2014 was a similar casualty of
Lid Seal Spydietous early on. Being an "Expanda forum" Id suspect the majority of the members who have a few km's on their vans will similarly be unsuspecting carriers of
Lid Seal Spydietous, finding the front lid rubber rubber seal sliced through. I suspect this is unique to the first incarnation of the hard lid, and wont be relevant to the newer variants of the lids.
I removed stike plates, bent them to match the lid slope, increased the seating face with 25mm angle similarly bent and placed under the bent original plate, sealed and screwed them in line with the body moulding and adjusted the catches to suit. Pretty simple remedy, but not according to Jayco who've been churning out this design fault that they've been aware of for 8 years
(I'd already bent the strike plates when documented it dawned on me. Oops. So Ive just propped it up in its original position for the pic)
