Well - dogs like to 'mark' their territory every where they go - don't see much point in doing that with the 6.5, but if you like leaving spots every where over several hundred-k miles, then you prolly won't need the CDR system, with it's added weight and hi-maintenance aggravation, to prevent main-seal leaks, eh?
