Turbo Diesel Register Introduction

Welcome to the TDR! Our goal is to give Ram Turbo Diesel owners more satisfaction in the ownership of their pickup. How so? Each quarter we publish a magazine with 25+ columns. Since the Fall of '93, the TDR has provided an open forum for the exchange of information from manufacturers to truck owners, from members to members, and from truck owners back to manufacturers. The quarterly TDR magazine, a 116+ page publication, features technical tips, maintenance basics, product evaluations, owner feature stories, industry news, vehicle history and development and more.

If you are a TDR subscriber, log in (top right corner of your screen) to access all the resources your membership includes.

New to our site? You may create a username and password for limited access to the forums as a registered guest. We hope you will consider an annual TDR membership which includes a one-year subscription to our quarterly print magazine, a copy of the annual TDR wall calendar, as well as access to all areas of our forums, digital back issues, and invaluable, downloadable technical publications.
