But because so many RVers are moving from tow dollies to tow bars, there are a lot of low priced used dollies on the market. Lots of new products out there. British Columbia subsequently stopped enforcing the breakaway system requirement, because there were no systems on the market. This adds a new impetus to purchase of such a system. Add a toad, and you may find yourself way over.
Some systems only brake two of the four toad's brakes.
Two years ago there were two systems out there. Now there are at least 16 different systems, because for the reasons noted above, the market looks attractive for new entrants. Hydrolic lines always have a potential for leaking, which of course can cause brake failure. Once adjusted to the toad, it requires no further readjustment. Disadvanage is will break cable if you try to back up.
