John Actually the refferance chart for mine show it at 14,000 with a 4.09 rear end and yours at 18,000 with a 4.10 rear end, and mine has the 4.10 rear end also. So I guess I can haul 18,000 total GCVW as well, but I have towed that plus the truck's weight before. Yes the options add up in weight as I don't have power window, power locks, carpet floor, power mirrors. It's a work truck. But the A/C is much better than my '97s. My plow weight 830# and I put 2 pallets of salt in the back at 5000# plus the spreader, and it handles it like it wasn't even there. One thing about Dodges, you get 1 ton axle in the 3/4 ton. the back is 1 leaf spring less than the dually's and front is the same.
