Re: PH top trim gasket folding under when closing top
We had a similar problem with our new (to us) 2002 SMB.
We're just back from Fresno where we had a new stove, bushwacker flairs and a ladder installed and a number of minor problems fixed.
We had that gasket replaced on the PH roof, and they added a strip of slick black 'tape' around the outside edge of the PH hole on the body. This allows the upper gasket to slide into place and seat easier. SMB said that it's now standard on newer models - don't know when they started doing it.
