Look at my hitch set up please....

For us to really help you a pic of the trailer and truck with the hitch set to your specs would help. You want the trailer to sit level and that cannot be determined from the pic. Also, and it might just be the camera angle but it appears that your chains are not vertical but appear to be at an angle. That is not good but again it could just be the camera angle. As far as the spring bars hitting the ground the hitch head has an adjustment and it could be tilted back a little too much. You want some tilt but perhaps in your case it is a little excessive. From what I can tell you have about eight links showing on the chains. You might try to get that to around six and see what happens, but that also probably would need a head tilt adjustment. Overall, from what information you have provided in the pic, it appears that there is room for improvement. More pics, more possible help.
