I think the point of my post is that we don't want to totally scare people away. We should qualify - If your towing will be "in the mountains with grades of more than X%. If your towing will mainly be on interstates and in the flats such as Florida, Eastern Virginia, etc.

I admit ... I would never tow in the "heavy" rockies with my Mariners. But I would tow from Florida to Maine with my Mariner.

I think also important is how you load. I am still experimenting with that. But that is another thread. Thanks everyone. I have learned from ALL of you. And I hope a few have learned from something I have posted. Have a great day!
