The GVWR and GAWR for the 5th wheel is 4218kg and 1950kg respectively.
As for the truck, the GVWR is 3085 kg and the rear GAWR 1770kg.
Some explanation of the numbers would be great. Is there any other numbers that I can provide that make the explanation more clear ?
Thanks for the help,
There are more numbers than that, and I have to try and figure out which is which here since you are metric.
First, let me send you to
www.learntorv.com where you may find some useful information.
The big thing is the pin weight on your trailer, in addition to the weight of the hitch, and anything loaded inside the truck could (and probably would) severely overload the truck. You could have upwards to 800kg+ of pin weight when the trailer is fully loaded.
Another thing that hurts is the gearing. Using the 2014 guide with an express model, you lose over 2000lbs (800kg) of "towing capacity" (mind, they don't rate it using a big box RV, but something with better aerodynamics). The tow rating for the 2014 is 3600KG and your trailer could weigh as much as 4200KG!
Last problem is your bed size. I believe
Etrailer.com suggests using a Reese Sidewinder/Revolution pinbox with this bed. Your other option is
Pull Rite 3100 series hitch for short beds less than 6 feet. That hitch itself can weigh 180 kg with all the brackets needed.
So, with a payload of no more that 635KG (using a stripped down express model as an example) before you exceed your GVW, when you add your passengers, cargo, hitch, and pin weight to the equasion, you can easily be well over that. If you have a high end model, like a laramie limited, you only have about 490KG of payload.
