Replacement Rear View Mirrors

I seriously doubt the wobble you mention is the mirrors, so before you pay the outrageous amount that everyone wants for new mirrors, check something out. I had the same problem on our old RV, a 2006 Hurricane. Turned out it wasn't the mirrors at all. When they installed them at the factory, they apparently didn't think the mounting screws were anything that water could seep in around so they didn't put any sort of sealer on the threads. As a result, the wood blocking inside the coach wall, where the mirrors are mounted, had rotted out. I tried several methods of repairing it externally (drilling out and filling the existing holes with epoxy, installing steel inserts, etc.) and they all seemed to last about one trip. The solution from Thor was the same that one of my mechanic buddies had made - drill through the entire wall, put a longer bolt with a spacer on it and a steel backer plate on the inside of the coach to keep the wall from crushing when the bolts were tightened. As the inside location would be hidden under the dash, this was entirely doable, but I traded it in before I got around to doing that.
