Nice rig, my Durango has the 360 and my van did too, it is a very strong engine and should pull good for you. I sold the van to a friend and he loves it will pull the steepest hills while towing his 4Runner or Truggie on his trailer at no less than 45mph. Should be a lot more affordable than that tank. My Durango is awesome even more power than the van, I chipped it and can smoke the tires off, even in 4wd.
