If I want to take both ATVs with me, I have to tow the 7X14 enclosed trailer to haul them. In order to tow that trailer with the motorhome, I must have an electric brake controller installed in the coach.
So, a dolly with electric brakes is not a problem. Of course, I can buy the trailer mounted brake controller from Tekonsha to add to the big trailer, and get the similar unit from American Car Dolly ($120 extra) on the dolly, and that will solve the problem rather nicely!
If you know for certain that you will never tow an electric brake equipped trailer with your coach, it is a moot point.
