Ok boys and girls, here is what I've learned today.
The spring arms have no visible damage to the knee joints or the joints where they attach to the trailer or leading edge. There is no evidence of the attachment points now or ever having been loose.
When manually retracting the tarp, it moves in easily. I used a 1/2" ratchet to do the work. I assume there is a mechanical safety or something which prevents manually rolling it out. There is an immediate hard stop when attempting to do so. While manually cranking the tarp in, I noticed while the tarp was in the outward most 40-50% of its range the spring arm tension would slightly push the tarp out while I was free wheeling my ratchet. Once it was in the last 50% of the inward journey, it was noticeably tight.
I deployed and retracted the tarp 5 times and it became noticeably tighter on each successive cycle. Something is binding in the center area of the roller. I do not see any way to remove the cover allowing visible or physical access to the roller area. There has to be a way, I just haven't determined what it is.
