Yep - a very good point as the TB Mass will vary significantly as most know dependent upon a number of criteria.
Van Manufacturer said could move axles forward a tad [but did not like the thought of that], configuring van and or loading it so most of weight over the axles would assist but still marginal given Pajero limitations. I had indications of weight on similar layout Vans from Van manufacturer that were around 2200kg [unladen] and low 200kg TB Mass, so if we added 2 large full gas cylinders plus some tunnel boot cargo plus two fresh and one
grey water tanks that would take the Van ATM
well over 2500kg. Given that immediately ATM over 2500kg Mitusbishi say revert to 180kg TB Mass and no other figure.
For me to acheive such a TB Mass [Based on my research] was going to be very difficult and meant a lot more weight rear of the axles so the Yawe [sway] factor dynamics would be compromised and create a less stable Van.
In all my recent learnings I noted that some Manufacturers are better at helping customers understand what the can pull and how to manage TB Mass, and certainly I felt Nissan [see Patrol guff on Nissan site] and Toyota were pretty good at that. I think Mits could do a bit more with the Pajero seeing as it drops from a maximum allowable TB Mass of 250kg straight down to 180kg when ATM increases by effectively just a few KG [from say 2499 to 2501kg].
Interestingly I note European Countries seem to want to keep TB Mass to about 6-8% of ATM.
