My wife and I are trying to decide which would be our next truck to tow our T T we are thinking about a ford F 250 with 7.1 diesel or a dodge 2500 with a Hemi with auto trans and four wheel drive, 4 ...
3/4 ton trucks for 2010 are capable of towing nearly any TT. Tow ratings are 9500+ pounds and enough payload to support the tongue weight, bed full ot camping stuff, and a family. If you have visions of 5th wheel in the future, I highly recommend a SRW 1-ton for the extra payload/spring rates ex specially if you want a diesel.
In 2010, Ford used a 6.4L diesel engine. The last 7.x liter engine for used was 2003 7.3L. Are you comparing a early 2000's Ford diesel to a 2010 Ram gasser?
