Ignore the max pressure on the van tyre placard and go by the max cold pressure as stated on the tyre and don't go over it, if a P rated tyre you will more than likely find that you will be on or over to get the proper pressure, using an XL or better still an LT tyre will allow you to have a good pressure and not be on the max, most important on a single axle.......... on really hot days don't deflate the tyre either as it will only run hotter......
Weights look okay, basically keep the GTM under the rating as well as ATM and all should be good, the 145kg ball weight is about perfect I reckon, youve doe a nice balance. the Territory being an MA classification vehicle means it doesn't have a GCM on the plate, an MC class gets a GCM, another stupid Boofacratic decision ...........
Scalies will look at the GCM (real world) of a rig and if good you get a green, if not then they will work further, ATM, GTM, GVM and what is rarely mentioned in mags, axle loads, if they get down that far your in the poo big time................. Just using some common dog when loading is bascially all thats needed, of course ignore TARE it doesn;t exist, same as load capacity they both go hand in hand, once you add things like bar work, extra lights, seat covers even or that set of bigger tyres, the load capacity drops, have seen some vehicles with the accessory catalogue bolted to their vehicle, theres only room for 2 bums.
The rig looks good and I wish i still had mine............
