I installed a Draw-Tite on my '96 and it was great for parking my open car hauler. Hitch installed using the sway bar attach bolts (easy) and required a small hole in the spoiler. It's also fun to tell people I can tow two trailers at once.
Draw-Tite's web site, shows PN 65033 front receiver for '03 1500s, why it wouldn't fit a 2500/3500 I don't know, maybe some of our resident experts would.
