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.

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...
The super hitch extension does support WD. I have it on my horse trailer. You really need to hit a scale. My 03 F350 with nothing in the bed scaled out at 7600 pounds with the rear weighing 3500. I had tires that were rated for 3750 and with my camper I was right there if I had it fully loaded. Add in the horse trailer and extension and wd hitch with some load rebalancing I could do it. I still went to 19.5s rated at 4500# each for piece of mind. These days with the same camper and trailer I roll with a Dually
