We towed our Conqueror Compact from Georgia to Nogales, AZ and back. Camped in Tubac and along the way (both ways).
At about 2000 pounds loaded, it's not a heavyweight but it's not at all aerodynamic. I could almost maintain 65 mph but not quite.
The Jeep had 255/85-16 KM2s, autotrans, and 4.56 gears on 2.5" lift, bumpers, winch, & sliders.
