@notsobigjoe, the two jacks on the left side are still installed, plus I have 6 stabilizers with 2x6's running the full length side to side. It's remarkably stable, but I'm still busting butt to get it done as fast as I can.
Spent an hour at Home Depot trying to devise what I need to fix er up. Only thing I could not find was 3/4 crown 1/2 staples like what it's originally put together with.
I take that back, ULINE sells them, but I can't justify an almost $500 tool for one project.
I did see here
https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27553842/print/true.cfmWhere someone was doing a very similar repair as to what I'm doing, minus the staples it looks well reinforced. So I am going to do something similar but utilize stamped braces and plenty of liquid nail.
Unless someone has a suggestion on where to get the proper joint staples :)
