Hello, we have a 2018 class C Chateau. The roof has a metal bar running across the front. There is roof sealant on top. See picture. Our problem is that one end on the bar is kind of loose compared to the other side. When we are on the road, we think the movement is causing the tears in the sealant. How long can be the screw be to secure the bar to the roof without puncturing all the way throu ? Or we should let the dealer do this ? Roof guarantee is over
only 90 days...
Husband is very handy but this is our first RV and we are learning.
