B+ motorhomes

I have a similar model and I found that the clearance lights above the cab had a leak as well as the seam where the rubber roof meets the fiberglass cowling. The other leak area I had was at the back and I had to do extensive treatment around the bathroom skylight as it's an area where water can puddle. I used that foil tape with the sticky black stuff on one side (it was discussed back in this long thread somewhere).
