towing opinions on car dolly

Ya'll talked me right out of the car dolly! The Uhaul dollies I saw had brake lights and directionals easily seen from the sides. harness just hooks to the one on my truck.
Also there is a +700 lb weight restriction for the vehicle thats doing the towing (U Haul) I dont anticipate UHaul making that easy for me to prove, or do I wish to involve myself with all that. So scratch that idea, and thanks for the input.

As far as driving the car, hell yea its road worthy but its not even close to comfortable (IMO) . 300 mile trip-mid summer heat right down to the Mason-Dixon line is something I'm not looking forward to at all. Car Trailer: I dont think the Ranger, even w/4.0L has enuff nut to do it without doing some tranny damage. I wouldnt hesitate locally if I needed to, but not 600 miles round trip. Definitely wont be spending that much $$ to rent a Uhaul truck+trailer! No chance.
