I ripped the floor out before the show so the floor saga continues. Nick brought the queen bed model to the show, I was hoping I (DW) could see the twin bed model. We may be headed south to Pensacola later this week and I plan to swing by the factory again to look at that model.
I use a multi-tool with the big round metal/wood blade to cut the glass and use the shell as a guide. I cut the top lip of attaching glass and try my best to leave the lower lip as a guide and lower attaching point. I have done partial and full rear deck replacements. There is not much difference in time or effort. If you do a partial replacement I recommend the patch go from side to side for proper support. If you do a full replacement you can clean and paint
the rear frame while you are at it. I guess it would help to provide more pictures or a video but when working alone on a floor job you pretty much have your hands full. Another note: Usually the rear window seal causes the floor issues, since I'm working in a shop the first thing I do is remove the rear window for access to tools and ventilation.
