I love my Grand design and I think customer service is outstanding. I have had my dining slide, curb side worked on twice now by Grand design techs in Indiana, and when I leave it appears to be fine and when I get home something changes either from adjustments or ride settling. Can others see daylight when slide is closed at bottom corner, Is this something I should just consider normal or what else can I do to correct it. I am really concerned that moisture and or critters will get in.
