Heinz, good write up. I noticed you mentioned your existing dampers are leaking (despite not looking old)
A watchpoint with AVO's is that they are not fitted with a top bumpstop on the ram, so if they become over compressed, it breaks the internal valving and they leak, I'm not sure if they do the same if extended too far, but it wouldn't surprise me
So, to others using AVO's be very careful to have a little reserve in the compressed length
