Don't listen to these guys. What you really need is a Dodge 3500 dualie 4-door long bed with the Cummins turbodiesel making 355hp and 650 ft-lbs of torque. You could then do long smoky burnouts leaving FOUR blackmarks and beat the Tundras in the quarter mile while towing your Airstream while they're empty
OK, so the truck is longer than the trailer....whoopdeeedooo
OK, I'd get the 5.7...IF I were buying Yo-ota.
My Cummins really will smoke the tires off though, and it will chirp when it shifts from 1st to 2nd and from 2nd to 3rd. TORQUE is what wins
OK back to our regularly scheduled programming....
