2014 F150 SVT Raptor or 2015 Sprinter 3500 4x4 as tow Vhcle

I'd forget about the Raptor, IIRC it has a payload of only about 1000 pounds.

I did some quick research, and a 3500 Express passenger van even with the Quigley 4x4 conversion is still less than the $55K Sprinter and will have much more towing capacity and power. If you go with a pickup, any of the big 3 run of the mill 4x4s should also do the job you want as long as you watch the payload and order the most powerful engine.
