So great ! Master design.

I have finished the full suspension version with efferman‘s larger boom and actuonix linear actuator and some litter change. Thanks all designers !

It looks spectacular and makes me immersive ...

Thanks Saberwing40k. I still don't quite understand what you mean, maybe is LDD cannot reflect the actual situation, but so all right, I can bold use of the existing design before, and change some parts.

I tried to build GMK6400 using LDD according to gmk6400_1.2.pdf, which is the version full suspension on all axles. But one of the problems I encountered was that there was a brick on the top of the beam, which limited the upward movement of the beam. I was wondering if the shock absorber could work properly? The other thing is that the version I'm currently recommending without suspension, but I still want a perfect version with full suspension on all axles, bigger wheels, more reliable features. But I'm new to lego, and it's going to take me a long time to try. (sorry for my english)
