I would have bought better tyres and suspension before those other things! Given the van is on for so long, suspension and tyres become more relevant. I'm on my second set of Bridgestone Duellers 697s after the first set got me 70k including the entire lap around the country with the van. Not one puncture or issue and we did test it out. Picked them up locally for ~$220 a tyre, which is very reasonable I think. I would put tyres above all else in terms of vehicle upgrades. They are after all, the only part that touches the ground.
Suspension is vital too I think for long touring with a van. Not just for the springs themselves, but everything else attached to the undercarriage that is supposed to work in certain directions. Think CVs, control arms, bolts, braces etc... We upgraded to heavy constant load springs to try and keep everything square. You don't need top of the line stuff... Many reputable brands out there across different price ranges. For the reference, we went with EFS.
But as Drover said, everything has its breaking/wearing out point. But think of tyre and suspension upgrades as stress relief for the car. Improving them keeps the pressure of the other points of the running train.
Just my opinion.
