" a TT can tow as comfortable as a 5er. "
Having newer towed a 5th wheel how can such a statement be made?
I have towed both and it is day and night between how each handles particularly when a large truck goes by at 80 mph.
When I come up on a trailer being towed I can almost always determine if it is a 5th wheel just by how much the rear of the trailer is moving around. Check it for your self someday.
