Need to find a site for 18 wheelers discussions

some time ago i found a site but now i cannot get back to it.i enjoy car talk but i have a few problems with a big truck one in particular freightliner.thanks for your help.

Barnes & Nobles has lots of truck magazines. I just know there are websights and things listed.

How about this one? There is a problem board that has some FL questions.
