Personally the TDR membership means much much more to me than pondering the . 0954 cents per day/ 35. 00 a year subscription. It's keeping tabs on firends, Whats going on, the magazine, general support, the TDR travel companion, and just being part of the number one diesel community bar none. I am not saying this as a Fanboy, Moderator, or a Brag artist.
When I think back to all the things I have done to this truck, performance related, troubleshooting, repairing and helping others, and the learning that goes along with it (Plus cost savings on having things done by a tech) I can't say that the TDR had nothing to do with any of it when it has had everything to do with it to some degree or another.
I do not know where I would be without the knowledge this site has given me, I would be out not only in cash, but out some awesome friends, a local club with a shop, events (some HUGE ones that are many states away). To this day I still thank god I subscribed here over 7 years ago.
For everything else there is mastercard, but spending 35 beans on the TDR ..... Priceless.
Hope you don't go as there is a long road ahead that the TDR may be able to help you out with.
