I think we can all agree, vehicle regulations vary immensely between states, and certainly between Canada and the U.S.
I've seen (and I'm guessing others have too) pick up trucks towing 5th wheels towing yet another boat trailer behind that. Not sure, but maybe I've even seen pick up trucks towing a travel trailer while towing a boat trailer behind. I'm not sure if the limits of such are based on total length, or weight. There is a chart listing braking requirements
Towing Laws | BrakeBuddy - Braking systems for motorhomes towing a vehicle
With gas motor homes, certainly those like the Georgetowns (which almost always have a standard towing hitch limit of 5000 lbs) has anyone ever seen multiple trailer towing scenarios? ie: motorhome with towed car (toad) towing a trailer.
Too much stuff right?
BTW.........Ontario Highway Traffic Act states total maximum of no greater than 75 feet (23 meters)
