Well, I am not familiar enough with the 453 to say. However, the 451, gas powered, is certainly towable 4 down. We've towed ours well over 2000 miles now behind the RV. A great tow vehicle. Easy hookup and unhook, no supplemental brake system, great run car about after reaching your destination, great gas mileage. Further, you never know it is back there because it is so light weight.
