[Cummin A Long]

I would try to a get a 5.9l 3500 duelly 5or6 speed no mega cab cuz with the 5th wheel you have to get a sliding hitch or something the cost a good bit.The 2500 would be very unstable with the much weight imo,I have a 2500 and with a 11k pounds on my car trailer its alot of sag in the back of my truck
