attaching frame cross members back to floor in coach

[cyndrcarter]

I have a 2013 Eclipse Evolution which came apart underneath. Have had a fabricator strengthen the frame and am replacing the axles per Lippert. When the frame cracked and the cross beams pulled away from the coach; some of the bolts were pulled out through the floor. Now that all is secure again I want to re attach from the bottom up, from the frame cross pieces into the floor. What would be the recommendation for re attaching? I have 1 1/2 " of foam, 1/8 " luan plywood, and 15/32 " plywood. I'm guessing some sort of wood screw and glue? Can't come from top down. Can't be too critical as there were only 2 bolts coming down originally. What are your opinions?

Thanks,
Cindy

Think outside of the box for ways to do it... One way would be to find places that are hidden, such as under a dinette etc. Come down fron the top where you can and into a new brace of angle iron or 2x4 etc. and run it across the location of the original bolt to another place where you can come down from the top.

Coming down from the top with large washers and bolts will be far stronger than any glue or screws. Do it right and do it once.
I have done many such projects. What seems impossible can be done with some imagination.

I agree with that.
