the one any only time i used a tow dolly was with a 1/2 ton dodge towing a wrangler. anything over about 45 got very interesting, would start to sway bad. It got bad enough that twice i thought it was going to loose it. The only fix was to let off the gas and slowly slow down. Touching the brakes would make it substantially worse
real fast. what did i learn from this.... putting anything with a high center of gravity and short wheel base on a tow dolly can get sketchy. With no trailer brakes when the shit hits the fan you have no way of applying trailer brakes to straighten it out. The lighter the tow vehicle the worse it gets. if you want to tow it with an Explorer (or any time you get a new vehicle and have not towed with it much) i would go rent a tow dolly ( or what ever trailer you want to rent) and try it out early on a Saturday or Sunday before there is a lot of traffic. see how it goes and remember, if you hit a big bump things can go bad real fast. Going for a test run before you have to use it will lessen the chance of you saying, well i have to get it done now so lets see how this goes.
