A 4dr long-box dually Comanche would be a sweet little tow rig. The 4BT would be good although they're fraking loud, somehow 1 4BT is like sitting next to 2 Dodge 6BT's side by side. They are just horrendously loud engines.
I just think it would be cool to tow your Jeep with a Jeep. Thats why I wish they would make a full size Jeep truck again. Even if it was a limited offering. Lets say something along the lines of the Powerwagon Package with a diesel option in a body similar to the Nukizer concept. 4dr, diesel, and Nukizer body on a Ram 2500 would be a sweet tow rig for any jeep. Especially if it came with the winch, lockers, and oversized tires of the PowerWagon.
