One thing I haven't noticed in this thread is the reduced capacity due to how far forward the bolt on forks sit. You can't use your machine's stated lift as a guide since that's rated at the pins. With bolt on forks, you're sitting 3 feet or more forward of that (whatever your FEL bucket measures). I use a carry all seated in the bucket and strapped in place. It works for carrying brush or small loads, but I can only lift a couple of hundred pounds that way.
I've worked out a way to remove my FEL bucket and mount the carry all at the pins which should make things a lot better, but I haven't completed it all yet to test it.
