Update:
The manufacturer got back to me this a.m. . They are backlogged on orders for the new version of their "model B". As I suspected it would be, it's virtually the same as their previous spring-loaded pin devices, but adapted with a longer mount in order to reach below the large Eclipse heads to where it can fasten to the arm. The longer mount configuration apparently necessitated the addition of an upper extension which engages the roller shaft rod for stability; see photo.
The price is around $63 which includes shipping, around $18 more than their other model(s). I'm not sure there's that much more to the extra bracketing that a guy can't make it for himself out of angle iron, stainless bolts and screws, and some quality paint, and use the $45 model; as usual, it's what your time is worth.
The concept can be seen here:

Attached is a photo of the new version. I will let you know when it becomes available.
Due to paranoia since the Canadian freeway fiasco, I've not opened the awning and don't recall if the inner part of the arm slides up that high; but in designing their own bracketing, one may have to use discretion regarding precisely where the bolts go through the arm, or carefully choose the bolt type.
Regardless of how its done, adding this device to our Eclipse would go far toward my peace of mind and being rid of that paranoia, so we could use the awning without fret.
