Hi Burgie
Looks great. My hoist is basically the same, may be a bit heavier build, but I found that the vertical beam needs side support. You are only secured with those two bolts onto the lower x member.
I have a bolt just under the pivot point where I attache two flatbars down to the outside of the lower frame.
Check this link or go to my website and find the section attaching body to frame.

I wish my welding would be as good as yours
Fritz
