Hitch extensions won't support a weight distributing (WD) hitch set up, along with the integrated sway control that many offer. No WD means the TW of the trailer is going to be dead weight and the hitch extension will magnify that force. If your TW is 720 lbs and you have a 3' hitch extension, that's the equivalent of 2160 lbs TW on the receiver....
As others have said, I would weigh the TC set up and get some real numbers as a starting point.
Thanks for this info - I'm currently looking at the SuperTruss hitch extension. They say it supports a WDH:
Heavy-duty design lets you maintain a high towing capacity and allows you to use a standard weight distribution system
Extension slides into both receivers of your TorkLift SuperHitch trailer hitch for excellent support and stability
Patented, lateral-support safety chains provide extra security and help to distribute weight back from the extension's receiver opening to your frame-mounted hitch
Not sure if this means I would be mostly back to my original 720lb tongue weight though...
