I pull a 8 ft open utility trailer behind my 5er sometimes when we need to drag more stuff along, otherwise I have a hitch insert to pop my mobility scooter in there to hang it off the back, but I don't have any trouble in the midwest states. A quick google search should bring up a few charts that show which states allow the double tow. there's only a few that won't let you, like CA has a restriction where it can only be a watercraft ( really ticked me off when I went out there a couple of years ago, I could have used the extra cargo space on an extended trip) plus when towing double, you have to be VERY careful where youget off the interstate.. A n extremely large fuel tank is pretty much a requirement for towing double as you can't just pull into any station and don't load the last tow any heavier than you and your crew can push, because time may arise when you may find yourself between a rock and a hard place through no fault of your own ( I had the moron parking staff at Silver Dollar City try to shoehorn me into the wrong lot one time and if I hadn't spent a number of years pushing a big truck, I never would have wriggled that beast through there without having to pull it apart)
