Releasing these going in to Spring / Summer is kinda dumb.
I NEEDED mud flaps in October. Needed. I phoned RA, I emailed RA. 'Uh... ya, they're in development but we don't know when they'll be released.'
I purchased the RB ones and am happy with the results - tighten up the hardware and my 'gaps' are minimal. At this point I'm not going to buy another set - RA has lost my order.
