I towed my 31 coupe from near Havre, MT to Tacoma, WA a year ago. I towed it with my 98 F-150 and a U-Haul trailer. Other than my half ton pickup sucking down the gas @ 9-11mpg (heavy load w/o overdrive) the trip was great. The trailer ran me $305 dollars for the nearly 800 mile trip. Fuel? Well lets just say thank God it wasn't with this years prices.
Some people have mentioned using extra tie straps and I agree this is a necessity. I used extra ratchet straps also and was glad I did. A word of warning with the U-Haul trailer is that their front tire straps that are secured to the trailer have a tendancy to slip off the narrow, tall Model A wheels. Secure it well and check it often.
