Welcome, we just traded our 2012 5105m for a 2015 5115m. We've only had it for a couple weeks, but it seems substantially stronger. We went with the h310 loader and with loaded tires it still needs a fair amount of weight behind it. I'm a little nervous about the DEF, but we'll see. The new cab is nicer too and a little quieter at RPM speed. So far it seems the clutch is a touch smoother. The brakes seem to be doing that excessive play on the first push until they pump up that some 5105 owners were talking about, ours never had that. So I will have to pay attention to it. the road speed is higher, which is nice.
