Effective Payloads

This message has been deleted by the author.

In trying to work out the best vehicle for one's individual circumstances, ONE basis for comparison is the effective payloads. The effective payloads vary according to the Gross Combined Mass (GCM) of vehicle and trailer in the case of the F250, and towball weight in the case of the Nissan Patrol. I have worked out the effective payloads below (it takes 2 messages due to the size of the message) with differing mass trailers and, given the vehicle mass, wheelbase, engine size, towing ability etc etc, I was very surprised that the effective payload of the F250 is the lowest of the 3 vehicles compared when the trailer mass is 3500 kg. I would appreciate it if my calculations could be checked. Thanks.

The effective payload is calculated as GCM less trailer wt less Kerb Wt. In this scenario it’s 7369 – 3500 – 3198 = 671kg . This figure of 671 will increase as the trailer wt decreases, with the maximum payload of 1021 cutting in at a trailer wt of 3150 kg.<o:p></o:p> <o:p> </o:p> (2) Patrol adjusted allowable GVM when towball wt increased from 200 kg to 250 kg, decrease GVM by 150 kgs therefore adjusted effective payload is GVM + 250kg – 150 kg – Kerb Wt = 700 kg<o:p></o:p>
