I have a 2011 Ford F350 Super Duty Work truck for sale. It was owned by the railroad system and was used mostly on the railroad tracks. The truck runs super and shifts great. 
I bought to put a tow package on it to tow my car carrier but am looking into something else.I drove it for a 5 hour trip from Virginia to my home in South Caroilna and had a smooth ride with no issues.
Any questions, please ask
