Al-ko self levelling

[jako999]

Hi all as some of you may know we have a new Niesmann on order, I’ve been thinking of trying to add self levelling to the order, it may be to late but the van is already delayed by 3 months, after all what’s another 6k the budget went a long time ago.
I would have thought it would have been a goldschmitt system like all the air rid they fit but in fact it’s a al-ko system has anyone got one and are they any good?

I would rather it be a factory fit at point of build then all the cables and so on are instaled and not just add one’s.

Thanks in advance
