Here is my situation. When pulling my flat bed trailer with my current 6 inch drop ball mount the trailer sits nose high. I would like it to tow level. If I were to get an 8 inch drop that would about level the trailer but create another problem. The back of the trailer has a folding ramp that will cause a high center problem when loading the John Deere garden tractor when the trailer sits level. Also my driveway has up and down areas that drag the rear of the trailer with the current 6 inch drop. What I need is a ball mount that is adjustable while loaded so I could crank it up or down without disconnecting or unloading the trailer. Does anyone make something like this? Thanks
