MDS didn't come out until 06 in the Rams. 05 in LX cars. It works great imho, my 05 Dodge Magnum RT has it and I really wish my Ram did as well. My friend's 06 Laramie gets 2 more mpg than mine when I've driven it. Easiest way to get it would be to trade up to 06 or newer 1500. Of course you won't get the sexy head lites that our trucks have! To swap in mds would require a different ECM and a motor from an 06 up. I guess if you can get 22 mpg on the highway, like my friend 06. You probably could check motor number against the chassis#. I've heard horror stories where the number under the windshield was swapped onto a stolen vehicle. I talked to a guy that built his Ram from 3 different wrecks.
