Thanks Linda,
I thought that might be the case with the table as original bridge to that area gap. I appreciate the advice on making a folding platform. That’s what I’ve decided to do for sure. I had another friend on TMC Facebook group make and send a video that explained how his went in. Super helpful to have a visual. The rails on either side will be the best improvement for stability and of course better material than the flimsy press board you identified!
Thanks all!
