I am pretty sure the tow capacity is based on the wheght of the vehicle and the strenght of the tow bar set up, I sure if you do a few specific google searched you will find a formula, other than that try tow mobs that run the old ftruck tow set ups??

Try this

http://fordtruckworld.tenmagazines.com/forums/

This would be the best place to ask.

A 1973 to 1979 F150 and larger forum, lots of stuff by the looks of it as well.

from "Xalent" on the forum


I have a 76 F250 4X4.
Rego papers show - tare mass 2340kg
- Gross Vehicle Mass 3493kg
- Gross Combined Mass 4700kg

So if your truck is empty and near Tare weight you can tow 4700 - 2340 = 2360kg
Obviously, as you add weight to your truck your towing capacity will reduce

I check the catalog at hayman reece.

http://www.haymanreese.com.au

Looks like they do a 2800kg towbar for a F250

FORD 1973-1993 R788 F100 F150 F250 Utility (E) $490.00 2800/250

The only spec anyone is going to care about is a manufacturers spec, although the hayman reece spec is probably a very good guide as i have yet to see a hayman reece towbar rated above the vehicles maximum.

Have a look at any GQ hayman reece bar. Mine is rated to 3500kg's. The car is only rated to 2500kg's.....

I would try ford. If you get someone reasonable enough they should be able to pull up specs on any vehicle.

there is something in the QLD Transport literature somewhere that says in the absence of a manufacturers spec you can base it on the GVM. Ill have a look through these mod booklets ive got.
