Well, I see you get rocks from small log autoload but you can't dump them. You can use the DUMP LOAD but the rock vanish and logs are dropped that can be dumped. Well, inless i messed some thing your better off doing it bridge the old way. I sure would like this dump bed if the rocks are what is dumped(I say pokingly) But I like this truck because he added the snorkel like the 4911.

Sorry about to long delay reply. The fact is, I don't know how to get the rock load to work properly. If I set it up the way it's suppose to be, you wind up getting a mixed load of rocks and logs that can not be repacked when dumped. So I took a shortcut and made it drop logs so the load could be repacked if needed.
