You will need to measure your wheel base and track (width) and take the measurements and a tape to a dealer. I have seen golf carts inside the bed of a pickup, but I have also seen them on platforms that sit above the box.
I drag a 4WD Suburban because it can be put into 4 wheel neutral and towed without modification. The Fords need a kit from the manufacturer and then can't be towed over 60 MPH, however there are some after market kits.
I don't know about the Dodge trucks, but here is a link to the guides published by Motorhome Magazine: Dinghy Towing and Dinghy Guide
You will probably need a long bed, and you may want a crew or extended cab truck.
