We are headed to Alaska from Tennessee in 2012. I am told or just rumer that I must have towing brakes on my 2000 Jeep cherokee when towing behind my Moterhome when I cross into Canada. I don't have them now and not sure if the expense is necessary. any help appreciated. I have a Gulf Stream Cresendo with a 330 Cat and love it. 58K miles with no problems..
