Update to 4000Kg
The Knaus sun Ti 650MF has a large overhang and although the MLW is 3850Kg its only 2000Kg on the back axel. The overhang means that if you put a small amount in the garage you are fight on the weight.
So speaking to SV Tech if we put semi air on the back and uprated springs on the front we can go to 2240Kg on the rear and up to 1950Kg on the front. Total for the Van is now 4000 kg.
The ride on the road is also improved as the steering does no need to be adjusted all the time. Running 3 Bar 45psi most of the time seems the best.
