Makes sense Rod, but I need the full 2300kg which is actually the trailer GTM not trailer ATM. Trailer ATM is the wheel load plus the towball load. Vehicles can tow a trailer with 2300kg on the wheels and say 200kg on the towball. If you drove the trailer onto a weighbridge and disconnected it so it sat on its wheels and jockey wheel it'd be 2500kg which is the ATM. A vehicle's towing capacity is the GTM.

So to do it that way:

XR6 auto kerb is 1770kg (5kg more for auto), plus 2500kg is 4270kg. GCM is 4395kg, leaving me 125kg for me (which I basically use), not even room for a toolbox, can of Coke etc. Even if I was to get super fit again i'm still 112-115kg as i'm 6'5", even when I was 18 and playing comp basketball and super fit I was about 108kg! The XR6T is worse, final figure is 110kg.

I want a tray back, and i'd probably put a hydraulic tipper mech on it too. I was looking at the XR6T because of the torque (533nM at 2000rpm). If I went NA i'd get the LPi engine (straight LPG) in an XR6 cab chassis, automatically comes with 1-tonne suspension. But, Ford won't allow me to option the XR pack (minus wheels) with the cab chassis and that is a deal breaker for me. So I was trying to get them to sell me an XR6T auto with 3/4 tonne suspension.

Here is the tipper mech, you can see the Falcon specific kit on the second page:
