Yes, I finally got it and installed it and am very happy now that it's all over.
VERY useful, looks good, protects rear of AS and provides good storage compartment (illuminated by the license plate light above, as it turns out...happy coincidence.)
The install is well designed and instructions are clear, no welding, it's a few holes to drill in the frame and self-tapping bolts...which are cheap hardware and broke off.
I had to supply better grade-8 bolts and tap the holes to attach to the frame, but otherwise it's a good and not difficult install. (Using one-size 1/32 larger drill than specified to make the holes likely would prevent the bolts from shearing.)
I'm very happy and recommend it, despite the $1K cost. (probably better than a deductible from a rear-end bump.)
