A gas v10 will get about nothing MPG and will require a lot of TLC! If you plan on doing many trips do yourself a favor and look for a diesel. I would look at nada.com to see what an outlaw books for, maybe check with a dealer also. I would say you could swap engines but changing from gas to diesel requires fuel,ecm,exhaust and lots of other changes.
Good luck on your decision
