Had the same problem with our 200 series, the difference is our 200 series has a 3800Kg GVM upgrade....... our 200 series has been set up for remote touring, all the back seats have been removed and the back has been racked out.
We have a spare wheel carrier on the rear and a 180lt aux tank...... The landcruiser site pretty flat when loaded but chuck the camper on and it drops about 10 to 15mm.
When we designed our rear racking we calculated weights and balanced the weight out to help load share over the front and rear axles, all the heavy stuff like fridge,
water tank and the 3 x 120amp AGM battery's are in the centre of the vehicle and down low.
The main concern is you can feel the weight transfer when travelling at high speed...... it'snot dangerous or unstable.
We had a look at airbags but I'm not a big fan of them and they do limit articulation....... our landcruiser has KDSS
suspension so the articulation is worse when airbags are fitted (KDSS give about 4 to 5 inches extra wheel travel).
I spoke to the manufacturer behind our GVM upgrade and they advised me to try and not to use airbags...... they have offered to design a new set of rear coils for our application and weight.
We are trying to bring the rear up another 30 to 40mm.
If you run near constant weights or you don't use it as an every day drive I would get better springs but if , but if you weights change considerately airbags may be the go.
There is no substitute for a when design
suspension system....... airbags are a quick fix solution.
