I have a 2000 f250 v10, i have 6000 lbs plates on my truck now due to transfering the plates from my half ton chevy. Well its time to renew and i know that i need to get bigger plates. The question is what size 12 or 18000 lbs? I dont pull a whole lot but when i do it is usually 6 pwcs at a time which are about 1000lbs each.. only do this maybe once a year.. what is the upside to getting 18000 vs 12000 is missouri and what is the difference between local and beyond local??? Any advice or anyone know the difference???
