Glad you all will recover in time ....Thoughts and prayers are out to you .
I am not going to second guess anything but i have hauled a lot of equiptment on trailers and the one thing i would say is i always put a block under the rear of the trailer for the load to rest on so it does not raise the back of the tow vehicle .
It is just one of those things i do ......
I do not post a lot lately but when i see a issue that i feel may save someone from harm i come out of the woodwork

Edited to add......
Mods this needs moved to the safty forum ... But please leave a Ghost post here for a few days so it will be seen. Thanks
