Hi profdant139,
I'll add 2 things to help the cause.
1. Drilling or welding to the frame. Express caution here as there are OK ways to do both or wrong ways to do both. We do not even know what kind of frame you have. If you want to pursue this idea, it would be best to post pics of the frame ane how you want to weld or drill. Then we can comment on exactly what you have and are trying to do.
2. I followed Larry's link. Cool!!! If you go with the beam clamp then there is no drilling or welding and it's simple. I would add one thing if you want to enhance it. You can add a jam nut on the clamping screw if there is concern about the clamp coming loose. Larry has reported his never came loose, and no reason to question that, but he also has torsion axles can have less vibration into the frame to start unloosening. Point being, adding the jam nut really does not cost much and can help the anti back off. I have seen some of them come loose on machines that had constant vibration without the jam nut. A TT bounces down the road does vibrate. Some more then others.
Good luck and hope this helps
John
