Fiberglass crack

I brought my pod out for the second time this year and noticed a crack in the fiberglass (front/part of the roof panel) that was not there a month ago when we used it last.  It looks like the break is coming from beneath and not the result of something having struck the pod.  Since we were leaving for a quick trip to WI, I put some caulk around the edges so as to keep water from penetrating and damaging the material underneath.  I have looked and have not found any other cracks.  Since we just got back yesterday evening, I have not had a chance to contact the dealer yet.  I am starting here.

When you compose the message, look for an icon that looks like a couple of boxes with an arrow pointing toward the top-right. That is the expanded editor. The option to post a photo will be there. Look for an icon that looks like a tree. You will need to edit your photo so that the size will be less than 1024 kilobytes (1 Mb). Any photo editor should be helpful to resize it. Changing it to 800x600 (or whatever ratio it works out to with the greater of them being the 800) should work. Then save it as either a JPEG (.jpg) or PNG (.png) file. Browse for that photo and upload it. Once you have done so, clicking Okay will paste the photo in your message.

Hope this helps.
