James, I can't tell you what you should or shouldn't do as far as the towing.
I can relate my experiences. I have towed with a car dolly behind a class a Winnebago, (Dodge Shadow). Also have flat towed a Jeep Wrangler behind a small 20 ft. Tioga class C. I didn't have any auxiliary baking for either one, and never once did I feel the need for it.
As far as lights, I purchased a set of magnetic tail/stop/turn lights, and plopped then on the back of the toad and plug the cord into the tow vehicle.
