how wide is a two place snowmobile trailer?

[LauraD]

We are thinking of getting a snowmobile trailer, but the guy we are possibly buying it from isn't sure if it would fit two snowmobiles. So how wide is the average one? We may also use it for a quad and a snowmobile at the same time if not for 2 snowmobiles. So we want to know how wide it would be to know if both of them would fit on there.
