I am by no means an expert and I can't say at this point, this won't work, but more information is needed.
If you haven't already, you may want to read some of the "stickys" at the top of this forum. Here are a couple I would recommend.
Do you know your vehicles GVWR and payload? What are the front and rear axle limits? Do you know the weight limits on the hitch, weight carrying vs. weight distributing? It is also very helpful to know the GCWR of the vehicle. I would be glad to help and there are several really knowledgeable members here, but more information would help in getting a reply.
