That said, even with the vehicle tied down I wouldn't think the stress would be significant (it's not like the recovery point is 3' long) and unless the flatbed tow truck has a head-on collision I can't see it making a big difference.
My thoughts too. I'm thinking despite the downward force, the Trail Tailor mounts are so stout the frame or fasteners would probably fail before the lollipop. Just speculation though.
