I put a mission together just the other day. I thought the kit was extremely well done, and it went together very nicely. Only took me two and a half hours to get it compelted. The shocks took the longest, and is what I think is the kits only weak point. I didn't have any problems with rough spots on the cahssis or top deck. And the diffs in my kit were very smooth, I guess it all depends on the person putting them together at the factory. I would have to say that all in all, Schumacher has a winner with the Mission.
