Thinking of renting a dolly from U-Haul to tow a car from Maine to Florida this fall. We've never towed before, so pardon us if this is a really stupid question. But--once you get the car off the doll...
I bought a tongue jack with wheel from Northern Tool for $25.. Swivels to store out of the way. Very light duty, rated at 1000 pounds but I wouldn't trust it for more than a couple of hundred. It still makes it very easy to move the dolly around. Jacked up all the way you can pull it by the jack handle at a comfortable walking height. Actually only paid $12.99 as it Was on sale for $17.99 and had one of their $5 coupons.
