I was waxing the coach for the first time the other day and discovered several cracks in the front cap . There were some right by the ICC marker light on the passenger side and several about the 3 center icc marker lights . I'll be heading to the dealer to see what they can do. In the 8 months we've owned it, it's been in the shop for repairs for nearly 3 months .
You might want to check your caps for similar issues ... here's a pic of the cracks on the passenger side
, but it's had to see due to the glare ( no doubt as a result of my outstanding wax job :-) )
