Towing 4-down you have just the weight of the dinghy plus the tow bar. If you use a dolly, you now have the added weight of the dolly plus the dinghy. In addition to the added weight you have to to with the dolly, you now have the weight of the hitch on the rear of the coach which adds to the rear axle loading.
If you choose an enclosed trailer, there is even more weight to tow.
