Cracks in Caravan windows - just a "heads up"

Hey Folks,
This might be of interest to some of you... We bought a new Jayco (17.55-3 OB) in Jan 2011. We havent done a lot of travelling yet and about 6 months after picking the van up I noticed hairline cracks appearing from the bottom of the windows and spreading upwards. The longest crack was about 60mm or so. Both windows on the "passenger" side of the van showed similar cracking. The windows are the tinted bubble type as sold by Camec.
I reported the cracks immediately to Jayco as I believed it to be a Warranty issue and they agreed. I knew that it would be some time before I could get to an Agent to have the repairs carried out. (2 to 3 days and about 900 klms round trip).
To cut along story short the windows were replaced by a local Camec Agent - I had to pay a call-out fee and labour. Whilst the Agent was here he checked the window on the "drivers" side and found that a crack had appeared in that window also. Camec had agreed to replace that window also (about a month ago).
At the time of the initial replacement of the two windows it was insinuated that I was to blame for the cracking and I was given "the benefit of the doubt" regarding the damage and replacement. There is no obvious sign of impact, scraping or anything else on the windows or caravan.

It may be worth checking your van windows for cracks appearing so you have an opportunity for a Warranty claim. I do hope though you don't have similar problems.
