On my 07 Ram, I replaced the stock mirrors with aftermarket mirrors identical with what comes on the 2500 or 3500 and love them. I had to give up the electric adjustment, but sure am happy otherwise. Found them for $200 on ebay. You can find electric version, but they are about double the price of manual. In the winter, I switch back to the stock mirrors. Its an easy switch, only (3) nuts each side.
