I have a 335DS no leaks at windshield but i just had a auto glass company send a tech out to re caulk my windshield. However i just fixed a leak in the back corner driver side, water was coming into the area behind the electrical breaker panel. Turned out to be coming in from corner of roof, area beside the trim piece where caulking had failed. Have read on here many posts from other GT owners having leaks from roof. So I got some EternaBond Tape and covered all 4 corners over the trim piece from top over the round side down to the drip rail. This tape is guaranteed not to leak for 25 years, sticks like nothing else and real tough to take off. When i did this i found the seal at the front passenger corner just about to fail as well. So 2 corners failing, so did all 4 while i was at it. Next will be to cover all seams on the roof with this tape. Also others have posted about water getting in around the recessed lights at the top of both front and back end caps. So I have added more silicone caulk around those, suggest you do this as well. Water leaks are the enemy on any rv, so find the source and fix as fast as possible.
