I’m currently pulling a skid loader at 11k with Tri axle gooseneck weighing 7.5k. Using my 5 speed 97 dodge 2500. It’s no speed demon but gets the job done. On good road can run 65-70 comfortably. I’ve been looking at 97 f250 4x4 with automatic and 92 f250 4x4 with auto. Would either of these compare to the dodge? I’ve tried autos with older dodges and had bad luck. My mechanic says the ford autos are lot tougher. I don’t mind slowing down to 60-65. Will run where it feels comfortable and can stop. Have brakes on all 3 trailer axles.
