I've been out and about and in true Scottish weather it's been pouring with rain at the weekends. The commonwealth games are on in Glasgow and the weather during the week has been outstanding.
On the last wet trip we ended up with water inside the TD. It took a hosepipe to recreate and find the problem. It turns out the water was flowing down the curve of the roof, reaching the galley hinge, flowing sideways and then pouring over and then lipping into the TD instead of cascading away from the body. This is the second time I've cut the hinge too short. To compound matters the roof join at the 4' sheet, split and I've added go-faster aluminium stripes. They look great and sort that leak.
ADVICE....
Before cutting the galley hinge flush with the body, do some water tests; in my experiment, about 1/2" 15mm is about right.
