Like my sig says, 400/400THM/3.54 axle, factory equipment, except the engine and trans have been rebuilt. I haven't checked it without the travel trailer; when towing that, I get 7 MPG. I recall my FiL telling me it used to get 13 mpg, but we put a 12" taller camper shell on it, so it's going to have dropped because of that.
