Sdtripper,
The links you show do not go to the same trailer that you pictured in your first post. My trailer is like the first post picture. The links show trailers with sides and expanded metal floors on them. They are rated at 2000 lbs GVWR, but the no floor trailer is just 1500 lbs GVWR and a GAWR of 2000 lbs.
I think Rich (Nitetimes) is on to it. I was using the wrong wording I guess. It flexes. There is nothing broken. That was the first thing I checked. I think if they would have put two bolts through the back mount, it wouldn't be as bad. The angle is kind of twisting.
So Rich, if I do as I originally thought, by putting a 1" or 1.25" square tube across the trailer above the cross member and in between the floor sandwiching (that sounds funny). I can bolt the tube and cross member together to reinforce the cross member. Am I thinking right?
Maybe I will go ahead and weld the tongue to the mounts instead of bolting.
Thanks guys.
