Where are you all mounting your hi-lift? I had mine up top on the horizontal cross bar of roll cage but moved it down below to help keep the center of gravity lower.
Mounting looks good, I like the high mount more, but that is just my opinion. I do have a question, I notice that you do not have a rear bumper, how would you use this type of jack without a bumper?
I had mine mounted to the front bumper with the same mounting supports. However, I removed it due to mainly riding in mud and never having good enough ground to place the jack on when stuck.
