Lisa,
Make sure that looking for "a few more opinions" doesn't equate to looking for someone who will support what you're wanting to do. Nobody on this thread that knows what they're talking about is going to tell you to go ahead and exceed the capabilities of your tow vehicle. It just wouldn't be safe or smart.
