Yep & Yep & this is the way I see it:
Trailhawk 3.0-litre EcoDiesel 4x4 (from FCA Australia - US figures are a bit different from ours)
GCM = 6099kg
GVM = 2949kg
KWT = 2393kg
Tare = 2340kg
Kerb Weight:
This is the similar to Tare Mass, but with a tank of fuel (varies in how much though) and without any accessories fitted..Kerb weight is generally defined by each manufacturer so is not really a standard specification..whereas Tare is defined by ADRs and included in the vehicle type certification certificate
GCM = GVM +ATM - TBM
= 2949kg + 3500kg- 350kg = 6099kg
Payload = GVM - Kerb Weight (I like to use Tare..it is a defined std so 2340kg)
= 2949 - 2340 = 609kg
Now since TBM is part of the GVM when towing:
Available Payload = 609 - 350 = 259kg
Loading up:
Bullbar & Winch = 100kg
Available Payload = 259 - 100 = 159 kg for passengers, cargo, accessories
Add roof rack, rock rails and aux fuel tank (full) say = 155kg
Available Payload = 4kg for passengers and effects
Assume passengers x 2 = 150kg (75kg ea & no luggage)
Available Payload = -146kg (yep that is minus aka overweight)
The purists here will say but you haven't included the fuel in the main tank & yes I haven't..This is usually the domain of Kerb Weight if it were standard as a full tank.. I've ignored this since things are bad enough as is.
Now how does the 3.5t towing look now?? or any other over 2t for that matter??.
Damn that salesperson (neutral gender PC gone wild)..No I didn't believe them.
Anyway someone check my figures..My head hurts after this..I've lost some weight recently but I can't be that skinny.
3500kg towing..Furphy?? you bet!! Anyway my camper is 1.9t and ball weight is 120kg so I think I can sleep at night.
