That's my thoughts on seeing the new
40k Galvanic Servo Hauler anyway. It'd need converting with a sizable gun obviously, but that could be do-able. It has a AM cog symbol on the side and the front reminds me a little bit of the front on the Trairos (the AM's transport vehicle).
That crane looks like it could be used largely as is in epic too - a giant crane for moving shipping container boxes around and the like. I plan to make some harbour and industrial terrain and think I'll pick one up at some point.
