If you truly want a manual, I would definetly get the '05...definetly a big increase in power (We have an 05 4 runner and you can certainly feel the difference) and better mileage, parts will be out soon enough for it. Also having an '03 D-Cab I wouldn't want anything bigger on the trail or camping then it already is...if it were me, I would pick up a year or old one with under 30k on it...use the extra $5k and do some lifting and tires...just my .02 worth.
