Hi Everyone. I have a 2007 Rincon with original equipment including the shocks. We use it mainly for deer hunting and hauling stuff around at our friend's farm. I have a 48 inch cargo basket that I attach to the receiver and as soon as we put anything on it the entire back end just squats and sags. I am talking a couple of hunting chairs that are not that heavy and it just automatically gives. Do you think I need to replace the shocks to fix the issue so that it can hold a load?
