Just a quick heads up, my Rig built by Silver Crown 2009 has always had a roof detail that concerned me.
the perimeter has always held water, I have seen this detail on Renegades and several other Truck Conversions. My rig holds water in two areas, this past weekend I came into a wet carpet in the bedroom, I don't care how good a sealent is standing water will always find a way. So I installed a couple of drains this past weekend that I put off long enough. I set a drain in the roof flush, 1-1/2" PVC, then elbowed through the sidewall. Went through a good rain, drains worked well, STREAM shooting out the PVC and off the roof. On one of the drains I am installing a diverter and in line filter to fill my fresh water holding tank.....check your roofs, more photos to follow....
