There are many vehicles that can be towed four wheels down without needing or using the Remco driveline disconnect system. Since you have not yet picked a toad I'd suggest you limit your consideration to a vehicle that can be towed without driveline modification. Check out the owners manual when you look at the car to see what it says about towing.
