Yup, this is one of those "throw it up in the air and see which way the wind blows threads".
There are so many variables in Ontario that impact insurance; where you live 416/905/519/705; how much the agreed upon replacement value (if you have one); age and gender of principal driver; Where you store the trailer; type of tow vehicle and potentially how many times you will be on the road with the trailer in tow, (retired or not). All these factors you haven't listed, so it would be very difficult to compare to others if they are not in the same location, age, gender,TV etc,etc.
I have a 1983 310 turbo diesel with an agreed potential replacement value of $80,000; I am 52, so a ways from retirement, live in the 519 area code, we use the coach from May to Oct, always stored in my driveway and I pay $365.00 a year. If I were retirement age or older, I have no doubt I'd be paying a whole lot more.
Per Mare, Per Terram and may all your campaigns be successful.
