I have a 2019 2500RL currently in storage but soon to be brought home. Last year before taking it to the storage lot for winter, I got up on the roof to inspect for any problems and to wash the roof. I check the roof when I bring it home and then when the season is over. While walking the roof I noticed that around the skylight for the shower the roof was 'bouncy'. There aren't any leaks and no signs of leaks. The roof isn't soft just kind of bouncy as if there isn't enough support. Does anyone have any knowledge of this or perhaps a similar Imagine with the same experience ?

Thanks,

Jim
