Gearing up to put slide toppers on the 397. Bed slide, kitchen slide pretty standard. I thought there was not enough room on the door slide due to the awning, but after looking at it GD appears to have lowered the awning enough to get the brackets above it without mounting into the T moulding. Does anybody have a 397 with a topper over the awning? If so, is the bracket below the T moulding?
