I've been wondering the same thing. Both of our children are nearing that 100 lb. mark and so are their friends. I have my unit in storage for the winter right now but I have been thinking about this. I was wondering if I took a 1x oak board and ran my router around the edge to make it look nice, stained it and fastened it to the studs in the walls if that would work. It should support much more weight than the two little stops mounted to the wall now support. Just one of my thoughts.
