Hopefully someone will answer, but if they don't, just measure the rear ride height, weight a few people, and have them stand in the bed right over the axle. Then just re-measure the rear ride height, and do the math. I need to do this soon myself, as I have removed a spring, and need to know when I get the right amount of tounge weight.
