I have a 2010 prostar, and with my 15 wheel all the way back the king pin is perfectly centered between my drives. my empty full fuel weight is 32700, my steers weight 12200, my drives are 12400, my trailer is 8100. I have a great Dane 48 foot split axel flatbed. My coil rack is about 2 feet behind my marker light. If i use that as my center point i am always 36 to 38k and on the back and light on the drives. And right about 12450 to 12500 on steers. If I move the load 1 to 2 feet in front of the marker light. I am 12350 to 12400 on my steers. 31 to 33k on drives and 33 to 35k on my trailer. I usually run 75k to 80k. If I load my trailer right my steers are always in the 12200 to 12400 . I might have missed it but I did not see were you put how heavy you are on steers when loaded.
