Crack in fiberglass at front slide

[tbirdconvert]

I have a new 3710 fl and when and after my first trip I noticed a small crack about 4" long at the corner of the front slide.
has anyone else experienced cracking of the fiberglass at the slide corners on the upper level.

Just wondering if this is a common problem. I never saw this with my other 5th wheels.

I'd call Keystone and establish a ticket and then take it to the dealer.

I have the 3711 and my slide is not cracked. It does not sound normal to me

It used to be a common issue with the bedroom slides on earlier Montanas before they started installing an expansion joint in the skin below and to the front of the cutout for the slide. I dunno how common it is with FL models. I'd imagine the skin stress would be similar bouncing down the road, hooking up, and unhooking.

As others have said, this is not normal. Contact Keystone and your dealer pronto.

My 2001 2880 had that problem and they put a cover piece on for expansion after doing repair on crack. There was flexing and something had to give and was a weak spot.
