As you can see there is one vehicle thats missing wheels
That vehicle has wheels, you might not see them for the following reasons:
1) You are seeing it from too far away, so it's LOD-optimized
OR
2) You have the SmallPartsRejectRadius tweak set too high. Default is 1.
In any case, if it's a dynamic object, you can't remove it with ADE, because it's handled by the Addon Manager. Those objects are usually controlled by the "Scenery Complexity" slider.
And in the others there's alot of ramp clutter etc that does add to the immersion i get that but it also clashes with user/AI aircraft
Same as above. The Scenery Complexity slider is there for a reason, and the objects are designed to use it, which is obviously way more easier and logical than trying to edit the scenery itself, and of course it's much better, because you can changed it without even restarting the flight.
