We're in the process of replacing the carpet in our '73 23 with vinyl, so I'm trying to get the floor as flat as possible. Turns out it has some accident damage when it was hit on the left side and it apparently bowed the aluminum crossmember that is right behind the door. With carpet you could maybe pretend you don't feel the dome, but I think with a vinyl floor it won't be acceptable. Trying to figure out what to do about it. I've now removed the dinette and galley cabinet so it is out in the open. The crossmember happens to be directly over the transmission crossmember and I'm tempted to drill a couple of holes through it and the transmission crossmember, get some long bolts and attempt to bend it back down. Unfortunately, the most pronounced bends seem to be right at the chassis frame rails. Anyone have any suggestions?

I figure by the time I have $10K into it I'll finally have a $5K coach...

Gary, That cross member is so flexible that it is not making a hump
in the floor. The plywood is one inch thick and much stronger than
the cross member, look further like the main frame.

Gary,
Over the transmission crossmember? That's right under the step. Maybe you
mean the next one aft, where the torsion bars end? If so, you need to take
a close look at the details of that crossmember: It's flat on each end with
the end mounted in rubber. The rubber's secured to the lower flange of the
side rail with a clip across it bolted at each end. In other words, the
crossmember can move about easily. Even if you decide it's sufficiently
rigid for your purpose, I'd advise against drilling into it, both because of
weakening it and because the torsion bar pork chop might well be in the way.
I'd use J-bolts with the hook end around the crossmember.
