Leak Over Cab

[TrekGreat]

Hi
Need some of that great advise
Have had a leak at bunk area over cab & have done just about everything to stop leak but it appears nothing has changed
My question is this::::
There is a neoprene molding that runs the entire length of exterior of cab & I assume this molding covers the seam or joint where the vertical sidewall material & horizontal sidewall material meet forming a joint or seam
I have not tried to remove this neoprene molding as i'm afraid I may damage it but at some point I may have no choice
If this seam or joining of the 2 pieces has not been sealed prior to placing this neoprene molding could this be where my leak is occurring????
A great deal of rain water passes right over this molding
Has anyone removed this molding or found out that that is where you had a leak??????
Seems to me this this the last place I can look for the leak
Appreciate your help & comments
I'm aware of the pressure test but the nearest camping world is a 4 hour drive & I don't trust camping world besides I find it a challenge to do things myself
I have a 2006 Fleetwood Jamboree 23E
Hope to get some comments
Thanks
Ted

You could do a pressure test yourself with a good fan, cardboard and tape. Place fan in a window and use cardboard and tape to close up the gaps. With all doors, windows, and vents closed, you should get enough pressure to expose leaks with soapy water.

Butyl rubber is used around window frames, I'm not sure of the neoprene molding you're referring to. You might post a photo. Also, the lights and any antenna in the roof are famous leak points. Have you removed and resealed all of those areas?

If the home pressure test doesn't reveal problem areas, the areas you suspect as leak producing could be sealed with duct tape and water tested to see if the leak stops with the suspect areas sealed.
